Observed on multiple Windows 10 PCs running Zwift. Two entire buildings disappear and reappear on Crit City; one on the left after the esports arena, the other also on the left at the top of the KOM, just after the banner. Appears to be the same building style with the white render feature to the ground floor in each instance. Screenshots below from a stream last night, so game is on the latest version. Timestamped videos included too, though not sure they’ll work embedded.
