Save failures

[greycat]

My character killed Old Man Willow, teleported back to Angolwen, ran around and shopped and stuff, then used Ctrl-X to save and exit. Later, I ran the game again, and I was back at the first level of Old Forest. And 2 experience levels lower. All the progress from my session was gone.

OK, so, killed Old Man Willow again, got another escortee killed in the process, and teleported to Angolwen. The yellow "Saving..." never turned off, in the left pane. Walked through the wilderness to Trollshaws and entered it. It still says "Saving...". Ran around, killed stuff... still says "Saving...". Now I'm worried.

Very bad sign! Looks like it's never finishing the save of the Old Forest, leaving this save directory in some sort of corrupted half-done state.

Removed the .tmp file by hand, then tried Ctrl-S in game. Got the same error in the log file again. Went to the bathroom. Came back, and noticed that my browser was even slower than before...

I'm having the same issue. Also getting ridiculous slowdowns that seems to be related to very high TPS (ticks per second whatever that means)

70000 ticks per second seems... excessive

Same problem when leaving Old Forest by teleporting to Angolwen.

NOW I'm pissed!!!

Game over...

Game simply closed itself... had just time to see something about signal SIGSEV being raised in luajit, with the following in stdout.txt:

[LOG] Bones casts Identify.

This has been addressed in a separate post and has been fixed. To circumvent the bug, press "5" to wait until you recall/teleport to angolwen instead of resting.

Not the fatal crash when identifying the Phial though...
