Is it right, that you can't open any island?
Oei, after half an hour editing, a new island, with the island editor 1.20, nord island, 512x512 size, schwerig type, while placing lots of rocks and rivers and buildable coastlines, the island editor suddenly, without any bug report went gone. No instance of the program running anymore.
Do you start a quicksave? While quicksave is the program blocked (in difference to normal saving!) and can't react. Today, I have a crash while a quicksave. I guess the saving routine don't along with the blockling save. So, please don't use the quicksave, because it's buggy! I will solve the problem in the next version.
Bitte den Quicksave nicht benutzen, der ist fehlerhaft! Ich werde das Problem in der nächsten Version beheben.
