Any idea which files are missing, and how i can fix that ?

Fabric 1.20.1
https://www.curseforge.com/minecraft/modpacks/bcg modpack with additionally installed CTOV + Wabi-Sabi Structures mods

Did you use any command before this?

No. 2 players were on the server, map wasnt preloaded (or pre generated).

i will add to this,i have updated latest on 1.21.1,i have about 250 mods(my choice only,no official modpack,basically just mods,no configs) and thanks to bluemap i pinpointed the problem to those lamp posts possibly with arrows for nearest villages
