This article is about known bugs in current DYOM version. This is the list of bugs of the current DYOM version. The information is taken from Chimpso's topic
Invisible Checkpoints[]
Invisible Checkpoints are an annoying bug that leaves the red halo of the chekpoint invisible when designing a mission, but still leaves the marker. It can be cause by making too many checkpoints.
Invisible Interiors[]
Invisible interiors is when an interior does not spawn. This usually occurs during cutscenes when the player isn't in interior.
Coloroued Squares[]
Cloured squares is an annoying bug when all text on the screen, including all subtitle and the "Mission Complete" text turns to couloured squares. Coloured squares is caused by stray '~' marks in text. This often happens when players text colour or they accidently hit the '2' key when SHIFT is held down.
Driving in circles[]
When there's an actor driving a vehicle and passing the points there's a really high chance that the drive will drive around circles at the points that DYOM user has set. This is one of the annoying bugs for mission designers.
Health Regeneration[]
When you lose health, you always regenerate your health slowly. PatrickW said that Health regeneration was not intended in DYOM, so that confirms the regeneration as a bug.
Though in the new version, Version 7 of DYOM, this bug has been fixed.
