This is the first issue like this I've seen. Admittedly though we might not see many builds with patch-package. Noted on the "Redeploy without cache" option.

Hey sorry you were having issues with Railpack and the cache. I see that you've figured it out, but I'm still very confused why it was happening. The next cache shouldn't be interfering with patch-package. What package were you patching? I'll see if I can reproduce it and fix
