I have in two PBMs run into a problem with one small set of units in the DEI, and using a CSV dump of the scenario files I think I found the error.
This is scenario 28-C (using extended map which I don't think matters to this error).
The 2/2nd Avn Sup Afd and the 3/2nd Avn Sup Afd are two of the small air support units the Dutch have. Many such units can re-build into one larger unit, and these two can as well. But when you do re-build them, strange things happen. In one game they combined (using the re-build button) into 1/2nd Avn Sup Afd, which could then re-build into the 1/2nd Avn Sup Afd again, ad infinitum! In the other game the two units simply disappeared when trying to re-build them into the larger unit.
Look at the graphic below. The first is a screen shot from before attempting to combine (re-build) them. The names of the units implies that the large unit (after re-build) should be named "2nd Avn Sup Afd", and that there should be another small unit named "1/2nd Avn Sup Afd" but one is not present at game start (nor arrives later), so perhaps there is a typographical error in the scenario file? I dumped the scenario files (witploadAE) to CSV files and looked. Sure enough (see the second screen shot in the graphic below), there are definitions for three small units (not two), and a large unit with the expected name. Also, the three small units point to the first small unit, instead of pointing to the large unit.
I changed the three units pointing to "5911" to point to "5910" instead, then imported the CSVs back into scenario files and tested the fix. All three small units appeared at game start (instead of only two), and when they got to the same location they combined (re-build) normally.
Hopefully this explanation is clear. [:D]
