Hi, I've got the problem that in my solo world I can't add fuel with a lava bucket to my seared tank in the tinker's smeltery. I've been playing minecraft for a quite long time and played most of the time with tinker's mods, but I took a break from minecraft and now I started a new world but my seared tank won't fill up and I don't know what to do anymore and I also searched up if any others had the problems and how they fixed it, but it's still not working. I've also checked multiple times if I built anything wrong or if I built it to big or to small, but it's no build problem.

Pls help me fix my problem
