A warning message is displayed when a hammer is hit on any objects.

I noticed that when a hammer is hit on doors, a workbench and other objects in a bandit camp, as well as on a minicopter, a warning message is displayed ("You've not been given permission to use syncPipes.").
I apologize for my poor English.

Odd. Is it only happening in the bandit camp? 

No. Everywhere

I'll look into it.

Looks like that has been there a while. Thanks for letting me know.
It will only show for players who have not bee granted syncpipes.user.

I'll fix it in the next update.
