Follow the first part of the line for where the file is located, in this case, using your "Line:34 "[Unit 6]" Sequential Order==" listing, that is the Type23 in "D:\Game \DarkWaters \Data \Roster \German \Submarine \SSTypeXXIII.cfg" ("D" for drive, etc.) In that file, notice the listings for units:
[Unit 5]
Name=U-2329
DOC=19441231
DOD=19450630
[Unit 7]
Name=U-2336
DOC=19441231
DOD=19450630
[Unit 8]
Name=U-2337
DOC=19441231
DOD=19450630
It goes from Unit 5 to Unit 7, missing Unit 6. The "DB_EqpLoadout.csv Line 37:
ALB_B17g_Bomber;D:\Games\DarkWaters\data\Air\ALB_B 17g_Bomber\ALB_B17g_Bomber.eqp;=="Eqp:9=41" Double Node entry==" listing is similar (this is just one of several). Just navigate into the folder, and note in the eqp file and you'll find
[Equipment 9]
NodeName=B09
LinkName=NULL
[Equipment 41]
NodeName=B09
LinkName=NULL
I didn't look any deeper, but from the looks of it, there are more than just that one like that, but only the first mistake is listed. Hence the need for multiple runs of Hebe's tool. The "missing" stuff is all too common, and can sometimes take some digging. Some of the findings are indeed rather cryptic, but in those cases, check the spelling... Also, a "mistake" might be listed in one file, but is actually in its related file, so watch for those...
Additionally: The use of
Notepad++, a freeware solution, or better still,
SweeScape 010 Editor (payware) use line numbers in the left-hand column of their text editor pages. This can help immensely in finding some of these errors.
