r2413
The case of figure, tunnel maintenance cost is wrong.
I will have a look for it.
This should be fixed in nightly too now.
The
if(sp!=NULL) {
you've added in r2414 isn't necessary, since it's already checked in add_maintenance.
And problem is not solved yet.
Vorzeichenfehler ;) (wrong sign)
Patch attached.
Solved in r2421. Thank you.
