[TFS1.3] Stage Skills Error

[aqubjukr]

I'm trying to implement a skill stages system on my server. It even works, however, when I use any spell with a player, the following error appears on my console:

Lua Script Error: [Event Interface]
data/events/scripts/player.lua:Player@onGainSkillTries
data/events/scripts/player.lua:896: bad argument #1 to 'next' (table expected, got nil)
stack traceback:
        [C]: at 0x005be450
        [C]: in function 'next'
        data/events/scripts/player.lua:896: in function <data/events/scripts/player.lua:891>

Players.lua attached.

That means "next" returns zero but you are trying to use the variable as table
