So yeah my modpack is kind of huge. I hope that you can help fix it. Since it crashed when I previewed my ranch house.

Oh no thank you so much! I am so grateful you took the time to diagnose the issue. I know its not always easy for mods to play nice when like 233 mods are present. So thank you sincerely for taking your time to explain the situation to me.

This issue is due to ArchitectureCraft. That mod is registering a base renderer for vanilla minecraft objects (like a chest in this case). This has been reported a few times but ArchitectureCraft hasn't addressed this yet.

I will see if there is something I can do since this only seems to be a problem with Chests. If I cannot I will have to disable the preview feature when the offending mod is present, sorry ☹️.

So I feel like a real dummy on this particular issue. After much debugging I was able to pinpoint the mod which was actually causing the issue (which wasn't ArchitectureCraft like I thought it was). This was actually an issue coming MalisisDoors which adds animation to the vanilla doors.

I have pushed an update to CurseForge and it should be approved in a few minutes. It will be version 1.1.1.5.

Closing this issue.
