Issue Description:

When trying to add a block to the tag small_flowers, I get an error that says "Tag cannot be null!"
I may also be missing something from the file that I'm unaware of. I tried to use what was suggested in the previous issue, but no luck.

What happens:

• Logging into a world produces a "Tag cannot be null!" error with the provided script.

What you expected to happen:

• It should instead register the block under the tag small_flowers

Script used:

• Gist

crafttweaker.log file::

• Gist

Affected Versions:

• Minecraft: v1.14.4
• Forge: v28.1.107
• Crafttweaker: v5.0.1.150
• Using a server: No

Your most recent log file where the issue was present:

Full Log (Crash report at the end is unrelated to this mod)
Error for this is located at [18:54:33]
Error at the beginning of the log at [18:31:14] might also be related.

Thanks, I'll try that.

Afaik, you first need to create the tag.
Try something like

<tag:minecraft:small_plants>.createBlockTag();
<tag:minecraft:small_plants>.addBlocks(<blockstate:mubble:fire_flower>);

I assume what kindlich said fixed this (because that is what I would have said)
