Description of the issue:

When the built in season timer changes to the holiday season (Christmas) and the storage crates are supposed to change texture, it clears all items from them and changes texture.

Crashlog:

No crash upon this happening

Versions & Modlist

Mod Pack: Dungeons, Dragons & Space Shuttles
Mods List: crash report with F3+C

Sure I will test to see if it does it.

The textures have zero impact on their functionality, so these two things shouldn't be related.
Can you reproduce this reliably by changing your system time?

Nevermind it was probably something else.
