i dont remember if there's a specific format for these ::3c
anyways uh i decided to try to play a map when it loaded into the critical error screen when starting the map
tested with a few maps (including Strawberry Jam lobbies, only beginner and grandmaster didn't follow with the same error) before deciding to try and see if a map from Into the Jungle worked (it did not)
based on reading log output before the error message (included in the snippet), i suspect that the cause is the climbable sideways platforms provided by Jungle Helper
not related to the one-way platforms it seems

I don't really get how it would happen
