This affects 3 too #7920

[nunodonato]

@eon-s added in, thanks!

[Einlander]

Does godot 3 still ignore scaled collision shapes?

@DimitriyPS added, thanks!

[eon-s]

Tested #7644 , affects 3 too.

@eon-s, @akien-mga asked to keep this tracker focused specifically on CollisionShapes and not collisions in general, so I guess that one doesn't qualify :)

#9105, #8153, #8103, #7281, #8607, #8558, #8910, #4591, #2314, and #1183 are all fixed/closed. (This list is in the same order as they're listed in the tracker.)

[Einlander]

There is also this one. #3947

[gururise]

Another collision shape bug #13835

[LinuxUserGD]

#12521 (after resizing the collision shape)

[LinuxUserGD]

#4831 is Godot 2.1.3

[Chaosus]

Added #21141

[williamd1k0]

I just found this one #14599

[eon-s]

This may need to be closed and make a new one for 3.1 and 3.2/4.0

[Chaosus]

I recreated this list here (for better visibility) - #24816 - all fixed issues are removed + re-targeted to 3.2
