Orders corruption issue after upgrading to 1126b

[FatR]

On the previous turn in my PBEM I (playing as Japanese) and my opponent upgraded AE from 1123v2 to 1126b. After updating, my opponent reported that the message saying that the turn was saved in other version of the game was appeared, even though I certainly did the turn in the same 1126b version he had installed. I might have violated the updating procedure by reflexively making an order or two before saving the turn file and upgrading AE. After he processed the turn anyway, sent it to me, and I ran it, I've discovered that my orders got heavily corrupted. Only the ground forces orders remained as they were. Air orders, including both missions and air groups relocation seem to simply have failed to register entirely, remaining in the same configuration as in the previous turn, which caused a massive disaster.

Can anything be done about it without rolling back the game version and redoing the previous turn completely on both sides?

Our turn files are too large to attach even one of them to a forum post (we're in 1945), so I've uploaded them to file storage:

wpae020 is the previous turn with finalized Japanese orders I've sent to my opponent (the file with version confusion), wpae018 is the previous turn he returned.

Just for comparison, wpae021 is the final version of the previous Japanese turn before finalizing and sending it, wpae022 is the current turn saved immediately after replay, without changing anything. It's easy to see that orders and even air group locations are quite different.

I recommend simply redoing the turn under the new .exe.
