Summoner's skills not working

[Jowy129]

Hello,

I'm trying to add Doram and their Summoner's class in Pre-Renewal. I added what was necessary from rathena/db/re/ in those files :

rathena/db/pre-re/skill_db.txt
rathena/db/pre-re/skill_require_db.txt
rathena/db/pre-re/skill_tree.txt
rathena/db/pre-re/skill_cast_db.txt

I changed the base 100 level requirement for some skills and changed the exp table too. The base level is 99 now.

I can add skill points and unlock all skills. But when I try to put skills in shortcut or use it, the skill icon turns red, like the "etc." tab (see the attached picture), and I can't move it or use it.

I don't know if I need to change something server-side or client-side. Any tips or help for that ?

Thank you.
