Describe the bug
So, I've been playing with my siblings on a new Flans' world and after getting to finally build our own proto titan, I've noticed that it breaks itself. More specifically, everytime I walk the core just gets damaged. Sometimes it gets to the point where I simply move a couple of seconds and it is already smoking.

The other issue is that it simply won't refuel using the coal refiiner.

I've tried other versions of forge and it just crashes, as well as the Alpha Titan and Zero Titan on local wrolds and neither of them work as expected.

Steps To Reproduce
Steps to reproduce the behaviour:

1. Craft a Titan
2. Equip it with the coal refiner and (possibly) obsidian boots
3. Mine coal / walk around

Expected behaviour
Coal refiner should refuel the titan as it mines coal. However, neither does it refuel nor does it save the mined coal to the inventory.

The Titan shouldn't just damage itself by simply walking (I believe)

Versions (please complete the following information)

• Forge: 1.12.2-forge-14.23.5.2854
• Flan's Mod: Flan.s.Mod-1.12.2-5.6.0-beta.8

Sorry for not adding much of a description, but the issue is as straight-forward as it is.
