I color coded my ender chest, and nothing happens when i sneak-right click on it with my ender pouch.
I'm running 1.12 now.
Previous ticket for 1.11: #49

I am having this same issue.

Works fine so...

@Captainaviator Please provide a debug crash report (F3 + C for 10 seconds, then release.), If you are in an FTB Utils claimed area or any other sort of claimed / protected area, please exist that area and try again, if it still doesn't work, you will need to strip down your mods list, I'm unable to reproduce this in dev, or any of my custom packs, it is likely a mod in your pack causing the issue.

Thanks, it appears there's more to this. Upon further testing, i was able to sync colors, but only if the chests were personalized (my apologies, i meant to update this ticket with that infirmation). The other ticket i opened about not being able to use diamonds turned out to be a config setting where our server uses totems of undying instead of diamonds, so I'll have to test in SP more using default configs to confirm that issue

Either way, I'm not sure if it's intentional about the chest needing to be personalized before you can sync colors though, or if its a bug/mod conflict. I might have to dig further and try disabling even more mods to troubleshoot

Thanks guys! I'm not using protected areas. What mod packs have you tested in? That would greatly help me narrow down the mods to disable

You should be able to sync a bag to the chests colour, whether it is locked or not. I can't actually provide my modlist as it contains many work in progress mods, but @gigabit101 may be able to provide his.

Thanks @gigabit101 !
I removed all mods and the issue was still happening, so i reset the configs to default and I started working again. I then tried each config until i narrowed down anarchyMode. When that is set to false, this bug doesn't happen. When it's set to true, you can't sync the pouch

Does your ingame name happen to have any interesting characters in it? Such as Unicode?

Also, in anarchy mode, you can only sync the bag to chests you own. So, either that name check is failing due to interesting characters in your name, or you don't own the chest.

Noted. My in-game name is limited to normal English keyboard non-special non-numeric characters. I am also only trying it on chests that I own and placed in the world

The chest you are trying it on, is it 'personalised' to you? There is legit nothing here in the code that would suggest that you shouldn't be able to link them..

By personalized, do you mean having a diamond/personalization item on the latch?

Oh actually, i just read back the comments here, so it works on chests personalised to you but not on chests that aren't. Is there any exception in the server console when you attempt this?

Ahh, yep found the bug. Nullpointer thrown on the server that is caught and logged by mc.

My admin didn't mention any
