• [x ] I checked the MineColonies/Structurize wiki and made sure my issue is not covered there.

Context

• Minecraft Version: 1.16.4

Problem description

I have L5 University, L5 Library, L5 School, and a L5 Barracks with 4x L5 Towers.

The advancement "Grand Garrison" does not complete.

The research "Piercing Shot" cannot be started. With a stack of flint in my inventory, the research button says, "Missing Requirements". I was however able to complete "Cleave" which also has a similar requirement.

The research is because Piercing Shot and Cleave are on separate paths, you can only choose one of the paths

Ah, yes, I didn't train Cleave. I am on the Piercing Shot path.

"Fear" is also un-researchable.

What do you mean "guard towers"? Barracks towers are literally called "guard towers".

@ravenbuilder934 they are barracks towers, not guard towers, the lang string is off

Yup I was checking on that
The lang string doesn't exist I think
I'll take a look at fixing it

Okay, when you make a PR, it can then close this issue here

I built another guard tower, and now I can train Piercing Shot. Thanks for the clarification.

But I still cannot get the Advancement Grand Garrison.
