I’ve found one quite annoying bug in platformer automatism. My game calls for some steep slopes that player can scale, so I’ve increased in editor max slope angle to 60 degrees. Unfortunately, it lasts only until GD is restarted.
And so: Value of max slope is saved (in object inspector it is still 60, but after restart of GD engine somehow still thinks it is on its default, 45 degrees and so I need to enter some dummy value there and then put back 60 to make it work.
