When playing 0.51 with a custom Umber leader I designed a custom unit and equipted it with a short sword I think. Now with 0.80 I am playing with Umber again. The earlier designed unit was still there but because the short sword was moved to blacksmithing in 0.75 now this unit doesn't wear any weapon anymore and has 0 attack. Not much harm done, I just deleted and redesigned the unit. But actually I am worried about units with short swords I have forgotten about and the KI still might build.

Maybe there is a possibility to auto-replace the weapons of units like that or to automatically delete obsolete units.
