Display MoreSomething changed related to DB on AKI 3.4.0-3.5.0 that causes to behave like that if values have fields that shouldn't been here.
Therefore the issue is either stacks or custom properties field.
It will throw errors like this, and will cause screen to blink and no bullets will be shot,Sorry about this one, whole experimental section went in shambles on release, this function does exist in backend but never being called out, i forgot to select it from right field, will be fixed in new version.
FOR BOTH OF YOU: avoid using experimental section, it's really heavy FUBAR.
And please check the comments, those already were answered.
Disabling the Experimental Tab fixed my issues, thanks!
