I'm back! Sorry for the delay. 
Took 2 days off.
Because loading has gotten slow, I decided to rewrite the mod loading system, it took a bit longer than expected.
Then I got sick, this also took a bit longer than expected. 

Loading is now faster a bit faster, but I found out that parsing the abilities has gotten really slow. That's probably something I should fix before switching to Godot.
