Custom items error

I never heared this before, so I cant really help you, things that might help:
Download a fresh copy from github and recompile it (ofc that applies only if you have changed anything)

The items are working fine, only the lag is annoying. We're not that experienced with XML and adding items, if you wanna see the XML check ht tps://paste.ee/p/WMbv3.

Reinstalling the source didn't help either

This is not a solution but here are some things I recommend. Add the XMLS to dat1.xml. To do it this way will require you to have some knowledge about adding the XMLS in the client as well. Also do not use remote textures, they can cause lag if too many remote textures are used (at least that is what I have been told). If you do not know how to add items by adding XMLS to the client and dat1.xml, I would gladly help you.
