Hello,

I'm using the latest version of Synthesis (0.30.7) on the latest steam version of Skyrim AE on Windows 10 via Mod Organizer 2. Shortly before the end of the patching procedure, I'm facing the following patching error:

System.IO.IOException: The process cannot access the file 'C:\Program Files (x86)\Steam\steamapps\common\Skyrim Special Edition\Data\Synthesis.esp' because it is being used by another process.

I have no other applications open on my computer aside from Steam, MO2 and Synthesis itself. I also restarted my PC to make absolutely sure, but the problem persists. I'm using the following patchers:

Any ideas what I might be doing wrong? Happy to deliver more information if it helps.

Here's the full log file if it helps.

It seems to be similar to (if not the same as) this issue: https://github.com/Mutagen-Modding/Synthesis/issues/395

Manually deleting the existing Synthesis.esp output file and re-running the patcher solved the issue. Maybe MO2 had a read lock on it somehow?
