Also having this issue. Have a standard .p4ignore setup based on Epic’s ignore, and have version control running smoothly other than this occurring. Have “reverted” but they populate the uncontrolled changelist after a few days so I’d rather not keep spending the time it takes to do the revert.
Is there any harm in just turning off the uncontrolled changelist in the editor settings and sweeping it under the rug for a bit? It makes opening the “View Changes” window a lot better doing so.
