hello,
ive played on server where it was possible to enhanch/support someone digging a trench. e.g. if its set up slow, more ppl can join with ace interaction ->faster the trench is digged.
dunno how that script was called or if its custom made. is it a feature of grad?

edit/
its a featere and active, but is it possible to improve/make the ace interaction point of it bigger? its hard to find it sometimes. i know its possible to outline the ace options in the list, but i mean the area of interaction point. often you have to cuddle with the other guy which started diggng
