First issue has been addressed before, but doesn't seem to get a fix. History step gets erased after 10 seconds, so you can undo only during these 10 seconds. Otherwise no undo, no redo. Huge issue.

Second issue, some pages get corrupted for no reason? Layers on these pages get disappeared and reappeared some times with no ability to access them. Can't move, can't see them some times and when the whole document is about to be exported, those pages give an error "There's an error in page 94" and the exportion is canceled. The only fix is to delete the page and recreate it one again, HOWEVER, when I did create one of them in the same page number as the corrupted one, it still gave me the same result, it was corrupted. I had to add 2 blank pages to get it to work. Like why? Does anyone else have the same problem? Please fix! I can't work like that and I have deadlines to reach.

Thank you,
Thomas
