I'll change the density to 1 for the next RUb mod.

Did anyone notice that there are two British Minefield#8s? They are Ordnance unit 37 and 148. Could this be an issue?

I think as long as the Ordnance numbers are different they should be okay. I wish Nico was still around-he seemed to know this stuff; he's also the one who helped me do the minefields ('helped' as in pointing out where I was an idiot, not as in he did anything that can be criticized). I've played several patrols and have yet to have anything bad happen. On the other hand, I'm still in the spring of 1940, and the minefields haven't been laid yet.

Are CTD's (in the case of dense minefields) more prone to happen at higher TC's.

Or rather... with good RAM specs and 1x TC can I worry about this less?

what i did in my own campaing that im working on was to add entrys in the messages_en.txt radio log so that BDU sends out warnings about minefields, this only gives a vague idea about where the minefields really are.
maybe this could be something that RUB would be intressted in adapting?

Well, I'd certainly be interested, if that's of any help.

sure, i can make it IUB compatible if you want orgy,
