[1900.20] Landed Detachment - EXCEPTION FUSE REACHED

[Knightpawn]

In the attached unload cargo (troops) from the planes next to Lolland airport
you will notice that each of the landed detachments has an empty unit panel (which is also the case if detachment is spit in groups of units of the same type)
After a while the fuse exception is triggered

The test file uses db v519.

However in the last CSP, the db version of this scenario is v508.

Did you update the db and the problem is related with it?

[Knightpawn]

Indeed I have rebuilt to DB519. What is interesting in 508 is that in the same circumstances, no fuse exception is triggered but some of the same land units seem to just disappear when unloaded.

What units and aircrafts are they?
