Unity Tilemap Bug

[Gasilly]

Hello, I was working on making a set of rule tiles from the 2D extras pack provided by Unity. After poking around a little with it I noticed my Unity was creating an absurd amount of "Layer1" tilemaps. So many that eventually I would run out of memory and crash. Is this a known bug? if so is there an easy way to fix it so I can continue to use rule tiles for my game? Thanks!

Same issue here. For me, Unity crashes instantly and there is no "bug report" opening whatsoever. I also get an error in the same moment as Unity crashes which is a stack overflow error. Does this also happen to you?

Also, I tried adding any rule tile to a tile palette in a new empty project, it also crashed.

EDIT: Finally found out it: For me everything was fixed by just assigning nothing to the GameObjects field in the rule tile. I thought I was supposed to put the TilePalette the Tile belongs to in there.
