So I enjoyed the save feature and resumed my game.  After some time i had about 250 villagers and the game got quite laggy.  At the end the game crashed.
 
OS: Linux

CPU: Intel i3-2328M (2.20GHz)

RAM: 8GB

GPU: intel onboard

Java Version:

java version "1.7.0_72"
Java™ SE Runtime Environment (build 1.7.0_72-b14)

Java HotSpot™ 64-Bit Server VM (build 24.72-b04, mixed mode)

 

 

Here's the part of the log which caused the crash:

Here is the complete log: http://binaryb.in/show/bcb3de

Can you reload the game, or does it crash on load now?

[holloway]

It loads and the game slowly appears (with ~1fps) but then crashes again with the same error.

Any chance I can get you to zip the save file and upload it somewhere so I can look at it?

 

It sounds like it's the mating AI glitch I've been trying to hammer out, just happened to happen moments after the save.

Sure thing, here it is: http://binaryb.in/download/d7b1e2

Thanks. I'll have a look at it as soon as I can get back to my desktop.

yay! Isolated and fixed the bug. It shouldn't happen again, at least not in Unstable 5 or later.

 

For now though - I fixed your save file, I can't promise the bug won't creep up. But at least the save will work now. The painfully slow load times are just from the entity module loading an excessive amount of images all at once. I'm going to try to optimize that before releasing InDev 12 stable. For now though, you should be able to load the game and wait out the lag. Then everything should return to normal.

 

What was happening was when a villager was in-route to it's mate's home and the mate died before the villager arrived, the mate no longer existed. So when the still living villager reached the home, the game ran a check to verify that he arrived at the mate's home (who now has been deleted) and the game crashed trying to check the non-existent data.

 

I just fixed the bug in Unstable 5, waited for the mate to die, and then saved the game. So, here's your save, less one now-dead villager.

It could always happen again in Unstable 4b, and considering your village was on the verge of starvation and breeding was going nuts I suspect it will happen again eventually. But I should have Unstable 5 out soon.

Thank you, keep up the good work.
