Hi hamsterPL
I’m following up to see if you are continuing to experience an issue with the draw debug line duration. If so, have you tried updating to the 4.6 version of the engine? This latest release contains a lot of fixes to reported bugs as well as a lot of great new features.
If you are not able to update or are still encountering the same problem after updating, please let us know by responding to this post and we will investigate the matter further.
Thanks
