After thinking about this save/load system once again, I guess I just overthinked everything and made it way too complicated... (well, as I almost always do). I do not need to recreate any entities, cause they are already created with proper model and action attached to them while level loading. All I need to do, is load their settings (position/orientation and some skills) from file, and thats all Hopefully this will go right (anyway, I got recreating from file working, saving the function name into the string, then reading it back and using engine_getscript works flawlessly).
