Is it possible that you're using a mod that changes the player inventory size?

If so, could you try the latest dev build?: https://dl.bintray.com/cyclopsmc/dev/org/cyclops/colossalchests/ColossalChests/1.10.2-1.5.0-156/ColossalChests-1.10.2-1.5.0-156.jar

I'm not able to reproduce this with the latest IT version on 1.10.
@KusanagiRyu I've added some debug information when it crashes, could you try the following dev build?
https://dl.bintray.com/cyclopsmc/dev/org/cyclops/colossalchests/ColossalChests/1.10.2-1.5.1-165/ColossalChests-1.10.2-1.5.1-165.jar
And send me the full Forge log when it crashes.

@KusanagiRyu Is it possible that you're using a mod that changes the player inventory size?

Nope, i seen that mod in Invasion modpack but i'm not using it in this modpack (Forever Stranded), unless you're refering to Bagginses mod and IronBackpack mod...

@KusanagiRyu Can I send you a dev build to try when I can look into it?

the one you offered to KristjanKr?

@KusanagiRyu No, that one is released already. I'll have to make some more changes in the future when I have time for it.

sure. what's the link to it?

Here you go Ruben; Crash Log

@KusanagiRyu Can you send me the full Forge log? It contains additional debug information.

full? you mean the launcher log? Sure, here

Thanks, that's it. I'll look into it later today.

Thanks for your time, Ruben

@KusanagiRyu What is the material of your chest? Is it by any chance copper or silver? If not, what are the dimensions of your chest?

Sorry for the delay. It's silver. 5x5x5

@KusanagiRyu Thanks, in that case I know exactly what's going wrong. Should be fixed later today or tomorrow.

Many thanks Ruben

@KusanagiRyu Could you try the latest dev build?
This should resolve the issue.

https://dl.bintray.com/cyclopsmc/dev/org/cyclops/colossalchests/ColossalChests/1.10.2-1.5.1-166/ColossalChests-1.10.2-1.5.1-166.jar

Ok Ruben, tested and it still give me error message, only slightly different; here. See you in 10 hours.

@KusanagiRyu I don't see any (colossal chests-related) crash log in there. I also don't see any of the debug information I've added in the previous version.
Could you send me the crash log as well?

It didn't crash, it gave error messages when I sort. Give me a moment I recreate the error to make log.

ok, Ruben; here.

@KusanagiRyu Ok, so it's not crashing anymore. In that case this issue is fixed, right?
The sorting not working seems to be #68, which is a not-yet-implemented feature.

i see... back to square one then... oh well... better than nothing. looking for forward to your future stable build.

My priority is always to get crashes like this one fixed.
Implementing the sorting feature is something I hope to get around to soon, but I have a lot of other things I want to implement first.

Thanks for your help!
