A bug was found in the updater of SkillSystems of FEBuilderGBA.
The display of "Weapon rank increased to" message does not work well.
I have created a patch to fix this problem.
In FEBUlderGBA ver 20181102.22
"Fix SkillSystems TextID 0x02" Patch
If you are experiencing this problem please apply this patch.
You can only install this patch if you are having problems.
FEBuilderGBA manages character strings separately from SkillSystems.
The place to decide the character string is defined collectively,
However, the skill system after 2018/02/17 (February) only defines "Weapon rank increased to" in another place.
I overlooked this string.
