In the latest 1.14 release, only the wood tank has a recipe.

Could you give me a log file, which is saved in (profile)/logs.
I need “debug.log“ file.

If you want to fix it as soon as possible, use old version.

Edit:
Before looking for log file, please update mod to v14.9.4.
You may not find recipes for tanks expect wood, but the log file contains information about recipe.
After update, run Minecraft and load your world to generate log files.
Then give me “debug.log“ file saved in (profile)/logs. If you can't find, give me “latest.log“.

In my environment, all tanks can be crafted so I can't reproduce the bug. I hope someone post the debug log that may help me to resolve this issue.
That means I don't fix it for a while.
