I've just received a PM about a possible change for this stage regarding the 1000 coppers limit (because you have to fix the cut in addition to your stage). If you all think that you're not able to build your track AND fix the cut with 1000 coppers, we could change that. BUT: There have been lots of tracks so far which used way less than 1000 coppers. So I think there's no problem with keeping the 1000 coppers limit as it says in the rules. To cut a long story short:
the coppers limit is kept as it is!
