Nope, i'm not changing it, sometimes overriding (updateIcons method mostly, just to use a fixed icon), but not changing a bit . Starting to look for typo .
EDIT:
The thing is, that in the basic item updateIcons method i'm using the same filename as in the array method, but in the singled icon method (i'm overusing this word a bit right now ) it works, spellchecked few times.
EDIT:
Ok, at last fount the seed of the problem, but still don't know how to fix it, when i'm registrering iconIndex it works, but when it's an Array it doesn't (even thou i'm calling a native method working for vanilla bow, i even tried to make that bow just by using vanilla ItemBow class it didn't work, and the warning remained the same).
EDIT:
Now that i wrote that, i realized i made many useless classes unless i add an +* system that will use the same icon for axe etc on different upgrades... Decided to give up on bows for now and rewrite whole code, because i made some noobish error that i'm ashamed of now . Thanks for Your attention i do appreciate that.
EDIT:
Code was revised, but the pull_0 etc won't load, the names are fixed, so are the textures. nothing overrides iconupdate etc.
