This mod is so useful for commands, especially when /summoning and /giving items. But it's always a headache when I have to detect people with @A[nbt={...}] and its pretty annoying to not get the autocomplete there. (especially because I got so used to having this autocomplete during other commands)

Thanks!

For me it gives autocompletion (Fabric 1.21.1, NBTac 1.3.9). Is it issue specific for multiplayer or some other version?

It could be multiplayer- im on fabric 1.21.3, and I use it on a Purpur server if that helps- I have not tested this in singleplayer

Ok, I was able to recreate this issue. For some reason it was working fine on a Fabric server, but had issues working on a Purpur server. I'll take a closer look at the cause and try to fix it next week.

Anyway, thanks for reporting
