Hey Knightminer,

When adding a bucket of fuel to the porcelian melter, leaving, then rejoining a world it will delete the contents of the tank:

This does not seem to be a visual bug.

Thanks!

Does this happen if the tank is not attached to a melter? Does it happen with seared tanks?

Also, does this happen if you place a block after filling the tank? Specifically in the same chunk.

Finally, can you reproduce with fewer mods? I've been using this build in my survival world for awhile with no issues.

I spent a bit of time today trying to replicate this. The day I reported it I was able to replicate it 100%, today I was only able to get it twice in 10 times. I'll keep an eye on it.

The one time it did happen for me today it did not need a melter on top and was a seared tank. So, it does seem that seared and porcelain both can be affected.

I'll keep trying on this for more info.

I've narrowed this down to being a bug with the tanks not saving due to a missing mark dirty call. Unfortunately, this is on Tinkers Construct's side to fix, so nothing I can do here. As I mentioned earlier, I have a potential fix in Ceramics which uses the same code, so hopefully I can port it to Tinkers soon.

This should be fixed by SlimeKnights/TinkersConstruct@f723968
