If you could do something about it would be great.
Of course it can be irritating for other players if they don't get a message for Building block within the extended tc range of another player
but also it's not easy to know where and when to set new tc's in the area around the main base.
There's just no clear mark when one can build a tc again.
It's trial and error.

I suggest reading the note on the plugin description explaining the issue and your options: https://umod.org/plugins/tool-cupboard-extender#note

Damn. Didn't see that. That helped a lot. Thank you.
