So start by unloading ALL your mods. then restart
then add them back one by one.

I would start with any addons that change the building grade (meaning twig, wood, stone, ect) while builng... I would look at BGrade and BuildingGrade to see if either of them call errors.

Another thing you could do to make sure its not a server issue is delete the steamapps folder inside your server and re run the server update for Rust, just remember to re update oxide/umod after that

Hello, did you found a solution @musser233?

I've same problem.... Removed BGrade and BuildingGrade, restart and it's same.... 

So start by unloading ALL your mods. then restart
then add them back one by one.​

I tried but without real success.... this error occurs randomly... I also tested several sizes of maps, different seeds...

the only solution found is to make a wipe map but between us, it is not the best because after not even 24h that the server is online, the error can occur and it is the drama
