This happend before [Not able to build floors](http://discourse.stonehearth.net/t/not-able-to-build-floors/15432)

And I have no idea what doing it, Reloading before it hits 1000 fixes it but it keeps coming back.

Hmm… This seems to be the same bug mentioned here: [[Res] [Dev 2620] error in prune\_dead\_listeners](http://discourse.stonehearth.net/t/ack-bug-dev-2611-looping-error/16564/5)

This bug has been Acknowledged by the Dev team and hopefully should be fixed soon.

It appears to be the game freaking out when you kill a goblin. Play in Peaceful mode until the next patch and you shouldn’t experience the error.

I had 2 footmen killing the occasional undead assailant (demoted to workers while there were no enemies) a few days into my latest playthrough and when the first armed goblin arrived I promoted them again and when they had killed the goblin i got this error spamming. I searched discourse for prune\_dead\_listeners it didnt turn up any results, so i figured i might post this:

```
develop-2611 (x64)
radiant/modules/events.luac:77: assertion failed!
stack traceback:
	[C]: ?
	[C]: in function 'assert'

	radiant/modules/events.luac:82: in function '_update'
	radiant/server.luac:19: in function <radiant/server.luac:17>

```

It also generated/spammed a second c++ error, pointing to the above one being the traceback. Hope there is enogh info in here 😛

edit: sorry for posting dupe and thanks for merge @Relyss 😊

So my stonehearth started to lag and i could not select anything i could just look at what the villagers where doing. I could not even go to escape to save and reload the game file. I also noticed that stonehearth uses a lot of cpu and ram so my question is what is happening with my game?

Did you get any errors before you started to notice the issue? There’s a known issue that typically happens during combat where you get tons of errors very quickly. You can tell this because the error popup has a number in the top right that just continually increases.

If that happens to be it, it should be fixed in the next release. A workaround is to save, quit to menu, and then reload your game any time that happens. Read about it here:

> [@\[Res\] \[Dev 2620\] error in prune\_dead\_listeners](http://discourse.stonehearth.net/t/ack-bug-dev-2611-looping-error/16564/3):

> Same happened to me game froze at 2700+ errors within few seconds. But none of my hearthlings died that time. But i can confirm there was a goblin spawn at this time. Lucky the game saved in background could continue game but after load got once: develop-2609 (x64)radiant/modules/events.luac:40: assertion failed!stack traceback: [C]: ?

If that’s not it, can you post what error you got and anything you might have been doing around when it happened?

i was not doing anything. I had people working the farms and restocking chests. But there was this goblin that tried to attack me, he failed somehow and then he started to go towards his camp and an error occured.
