Issue Area: Engine Issue Type: Display Impact: High (this is visible to all players playing my game) Frequency: Constantly
It started happening since @Tiffblocks enabled a fix to a related issue.
This is the reason why this bug should be fixed very quickly because e.g. in my game which has more than 800 concurrent players there are signs in the lobby which are relatively important; however, due to this bug, these show nothing.
This is a serious issue affecting my game as well. Before, this was happening on some lower end mobile devices, but as of yesterday it is happening constantly on all devices. I started receiving bug reports about this after 8pm est yesterday, if it helps.
