Problems After Mod Distribution

Im making a mod and whenever i test in within Mcreator everything works fine, but once i distribute it to a jar file and test in game then i start getting some things not working such as:
One of my liquids having the texture but not the color

Weapons not working (swing and right click procedures)

And other things important to my mod

I've spent days reloading code and gradle, testing in another workspace and even on diffrent devices but nothing seems to fix this issue for me
