It's not fair to claim modders are not interested into this problem. The lead developers of this mod are excused until further notice because of tons of work in real life (see stickies), but several participants to DLV looked at this problem.
It has been confirmed that there are issues (see Bug Thread) and fixes have been proposed. However, genuine bug-fixes for the core DLV will have to wait for the lead developers to return to gaming. the Move-Capital mod has implemented a bug-fix for this problem, check it out if this is really upsetting you...
Be patient with our the DLV-team, they did an awesome job on this mod, they did it in their free time, and free... Not many people want to give up that many hours of gaming-time (I know I wouldn't
)
Cheers...
