For me personally, the save loading crashed when I used the F8 button. When starting the loading from the menu, everything was fine.

In the old version, it also crashed on the 2nd or 3rd save loading. Now, to save, it often starts to lag... I switch to the task manager and reopen the Heroes window (there are also some lags there), and the ability to save appears...
In general, I wanted to test (I played through the first scenario of the old version). The author has clearly done a great job, but Askh also sees it, and I tried.
I'll go test some scenario from the upcoming new campaign.
