Ok, so here is the deal: Sometimes my prefabs that are hooked up in the tilemap editor will get duplicated after committing the map. I have no idea why it does this, or how to reproduce the error. I just know that it happens sometimes. It will literally duplicate every prefab instance in the map, and once it is committed and I look at the tilemap render data, I see two of every prefab (with the same name, so it will say for example coin 1, coin 1, coin 2, coin 2, coin 3, coin 3, etc. Re-editing and re-committing does seem to fix the issue sometimes, but sometimes I won't even notice there are duplicates until I start noticing slowdown. Any ideas what could be causing this? Thanks!
EDIT: When I look at other tilemaps in other scenes, some of them I am seeing are duplicating up to 5 times! Eik..
