I wish to extend my previous suggestion: Make Sticky piston with Sticky resin instead of Slime.
Instead of using Sticky Resin on just pistons, how about using it on all recipes that use it? Including but no limited to: Slime Blocks, Leashes, Magma Cream, and so on, even on other mods's recipes, I know theres a way to say to the game that sticky resin is also to be seen as slime, so it kinda makes all other recipes, even from other mods to accept the sticky resin instead, idk if it will be hard to implement, but nevertheless the suggestions is here.
