Nope, nothing changed. I added both "Amxmodx" and "amxmodx". It's interesting though that if I add the package as "amxmodx" it doesn't even register it, but it works as "Amxmodx". The console says only this:
PHP Code:
xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 0
error: The settings file "res://Packages/amxmodx/amxx.sublime-settings" could not be opened
Package Control: Skipping automatic upgrade, last run at 2018-07-17 14:22:32, next run at 2018-07-17 15:22:32 or after
I can't even click the "Edit Settings" button in the AMXX toolbar - it gives the error above.
