Array index is out of bounds Skinned mesh renderer

Hello, I’m having a problem with skinned mesh renderer customization on my project, basically when i change meshes this error pops up:

It doesn’t seem to broke anything, but this error can be really annoying while working on my project, I already had this same error on previous projects, but it seemed to “fix itself”.
Anyone knows any fix or something I could try out?

Appreciate.

Fixed by using a larger base shirt on my base fbx model.

Edit: It broke again…
Edit: I fixed again by changing the default mesh on prefab

This may be “annoying” in the editor, but when you go to make a build, an error like that could cause your game to crash completely. If this is your own code causing this error then you should debug and see why you are trying to access indexes that are higher than the maximum.
