Running RR2 6.3.0 on 1.14.4, it appears to access a class from Iron Chests ("GenericIronChestTileEntity") before Iron Chests registers its items. As a result, right clicking on nearly anything in-game writes to the server console that "IronChest compat did not setup correctly". Obviously, this drowns out any other meaningful console output, and causes unnecessary load.

Notably, I can still craft iron sorting chests, and they still obey their set filters, leading me to believe that things still registered correctly in the end. The issue is entirely console-based.

Log from my server containing the issue:

I'm also having this issue, but my log is 900KiB and won't fit on Pastebin. I don't even use the mod, so you don't have to craft anything to get the errors.
