SH3 Commander problem.

[JFU]

Hello, i tryd to search the forum but didnt even really know what to search for, but my problem is that sometimes maybe after i have saved 3-4 times in my patrols, when i want to play and try to load the last save everything goes good but when the "Not so long ago" message comes the game crashes, but i did notice that the letters of the name my save has had changed to often " TKV" or something random like that.
I have read that it does not work well to save while under the sea so i avod that, could i be doing something wrong when i save? I also try to be betveen lands in the middle of the ocean when i save.
Anybody that knows whats going on?

You do right by avoiding saving whilst submerged, but another thing to avoid is saving whilst any other vessel or aircraft is within sight, or marked on your map as reported.
