I get this problem when my UW2 bot trys to use the skill deathly paradox.
This is a GWCA bot.
This is the line code:
UpdateStatus("Putting up SF")
Cmd($CA_UseSkillbarSkill, $SKILL_DP, -2)
UseSkill($SKILL_SF, -2)
If you need more info to help just PM me. Im paying 100 ecto to the person that fixes it for me
