I don't see any rules in the ignore configuration files by the way

Thanks! For our build we needed immediately we ended up deleting the particular prefab that was giving us issues and rebuilding it to get the build out quickly. We are now running into the exact same problem again with other prefabs. Again, I think it has something to do with the merge. I'll set up something with PlasticSCM.

I have this same error and also created a forum post here. I haven't been able to make get my scene to work. Desperate for help! )

Our team has been having very bad issues with PlasticSCM the last few weeks. It first appeared a few weeks ago when one of the pre-fabs was randomly disappeared. No idea how that happened, but ended up copying and pasting the file from an old changeset repo.Also every time someone opens unity, there is always pending changes that appear in plastic even if no changes are made. We have the compare data checkbox not just the timestamp in the Plastic options.Next was that a different prefab would keep getting disconnected and we would lose all work on a branch which happened a few times. We think this could be due to a merging bug. If we revert to the latest changeset and play in Editor its fine, as soon as we run the build though that pre-fab goes missing and then the game can not play in the editor.Today, after our team redoing the work that was lost due to Plastic, we were trying to do an Android build and multiple errors popped up as soon as the build started. See attached file for screenshot of console.Why are we losing data consistently? Why are there merge issues that look like they only appear during the Android build? Please help as this is holding up our studio. See attached photo for a screengrab of the errors after attempting to build.Unity version: 2021.2.9f1Plastic version (aka Version Control Package): 1.15.13 then upgraded to 1.15.18 to see if fixed anything - it did not.
