Game Update 1.18 - October 20th, 2021

@Zachary_Mazin may I ask on which platform you were running Zwift when you experienced your gradient lag? (Windows/Mac/Android/iPhone/iPad/Apple TV)

@John_Blumenthal I’m afraid the 1.18.1 patch does not address the “U-Turn” issue. That doesn’t mean there isn’t a plan for resolving this issue.

I think you will find you can perform a U-Turn anywhere in the game without issue, until the Zwifter makes an attempt to U-Turn exactly at the finish line of route completion. For now, please try counting to ten before U-Turning after completing a route. This should allow the U-Turn to complete normally and avoid this issue.

This issue seems related to a fix added to prevent an exploit involving U-Turns on route completion. It may be that completing a route and performing a U-Turn causes the player avatar to get stuck in a U-Turn that never starts, hence being stuck at the forced lower speed for U-Turns, and the inability to make subsequent U-Turns or choose intersection decisions.

Once the player avatar is stuck in a U-Turn, there is no way to recover the normal behavior besides shutting down and relaunching (on desktop) or force-closing and launching (on mobile).

Windows 10. Thanks Mike.

  • Fixed an issue which would sometimes cause long straight lines to appear on the map during route selection.

Sorry team, the fix didn’t work. Whatever was done, it has now caused the bug to happen for me - this is the first time I’ve even seen or had this bug, never had the straight line issue before this update.

PC app still freezing for me after 5 mins, or less, within a course. Android app and comp app all working fine - just still seems to be issues with PC.

A post was merged into an existing topic: Hiding option for Zwifters with steering option

No issues at all here, you’ll need to give a full run down of your specs and what problems you’re experiencing if you want others to be able to offer meaningful help. :+1:

Might not help but you’re already out of date, there’s been a patch to 1.18.1.

For reference; and yeah was just posting up an “issue flag”.

AMD Ryzen 5 3600XT, 32GB DDR4, Sapphire 5600xt (latest AMD drivers), windows11 :wink: , system running entirely off NVME SSDs, during Zwifting I’ll only run ANT+ off pc. Latest version of Zwift patched this morning, hadn’t been on during week. Have also completely reinstalled Zwift.

I’ll try again, and see what happens and report back. Have just done a 5km then 10km on Zwift Android, all ok.

Ha, I wondered if was the same chap from the group. :wink:

Yeah there’s absolutely no reason you should be having crashing issues based on those specs. Beyond the known problems, there’s nothing fundamentally wrong with the game on PC. Are you running any overclocks on your CPU, RAM or GPU? Zwift is incredible at causing system crashes even if your OC is stable in literally everything else. So back those off if so. If everything is stock then I’d suggest you have another problem, possibly hardware related.


absolute disaster after the last update. I have never had problems. But today power drops ( with ant and bluetooth),
all data disappears from the screen,… i use Android app.

Ha back, yes indeed! :slight_smile: I didn’t even make the connection.

For note, I’m putting this down to the AMD drivers and latest Zwift. Grabbed the latest AMD drivers, not relying on Radeon software to detect, and reinstalled - then complete Zwift reinstall. Managed through a complete course. I’ve not touched anything else.

Def one to watch for early Win11 adopters, especially if coming from Insiders.

I was lucky enough to fly once. I felt like ET!

Patch 1.18.1 installed.
Is there a workaround when the U turn select is busted. I’m not in a near a sprint and it does not work. I’m just out cruising and forced to quit ride as I’m up against a climb I don’t want.

Hey, after adding the update, my Zwift won’t sync with an hardware. This is a real pain. Had to use Rouvy to get my ride done.

Hi Fernando, I have the same issue. Super frustrating. I’m only had 1 hour free from my family today and I spent it forking around trying to get Zwift working.

Well I’m working fine less for the scroll bar on routes, but mouse wheel solves that. :+1:

Thx for reacting fast on the reported bugs. Some hours ago I seemingly applied the update. It seemed to me that my heart rate was monitored slightly higher than usual.
So far I have never had a maximum heart rate higher than 194 bpm (and that was year ago). Today according to zwift I had 201. Well, I went deep at a point, but…

I wouldn’t report that, if Eric Schlange would not have written somethin similar about his yesterday’s race…

Does the “plan” involve rolling back the change that prevents you being able to make a U turn , or just to stop you experiencing any issues if you try ? There are surely better more robust solution to the stated exploit ( like making sure the user went through the start and has followed the route ) rather than a dirty solution that removes ability to change direction (and without any UX feedback on feature being locked out) .

Read the post that is specific to this issue.
