I discovered a problem with residual data similar to
**.py script errors post while trying to eliminate CTDs using smaller mod lists than I normally used. To my surprise, I found these files leftover in the Silent Hunter 5\data\Scripts\Menu folder shown below in the attachment. I alt-tab (or ctrl-alt-delete) and found the **.py error window. The problem turned out to be newer **.py files compared to stock.
Multiple times I tried to start a campaign using silentotto with a smaller modlist I was surprised to see how long the game was still taking to load.
I disabled all mods and the **.py files was still there. Over the months past, I have disabled all mods during CTD testing. Everyone remember silentotto CTDs!! I never thought to check for this Silent Hunter 5\data\Scripts\Menu folder folder possibility of errors before.
This time I manually deleted all **.py files that are not stock. Thank goodness for the archived 1.2 silent hunter DVD to compare to. I reenabled all mods according to my original mod list, disabled them multiple times for test purposes, BUT these **.py files are no longer there, which is supposed to happen.
