[Q]

I tried a value >100% for maintenance limit in the settings.txt file for the race I observed. No effect.
The problem IMHO is that the beta-testing for SE IV works suboptimal. I do not criticize the beta testers - they do a great job - but the system. If you make a fix like the one of the maintenance limit, MM should give a couple of beta testers the precise job to check it. As far as I know (please correct me if I am wrong!) nobody coordinates what the beta testers actually test. It's open to everybody what they do and therefore some features are never really tested and bugs persist for years. Another example is the "change bad intel chance" ability that never got to work.
For SE V this should be changed IMHO.
