Should be following some kind of general pattern to ensure we avoid this issue. Might be easy to throw in some workarounds to fix these specific occurrences, might be more difficult to rewrite things to be more conducive to avoiding the issue altogether. Unsure.

It was indeed easy enough to throw in some workarounds to fix the specific occurrences, but not much has been done yet towards preventing the issue in general. Fixed these specific cases in https://github.com/sto0pkid/AutoNomic/commit/5f896b9cdad7db43fc6496f856311b5a41eeefcd
