buggy skill_xp_multiplier

[nikto0001]

If I use a talisman on which I have set skill_xp_multiplier to a certain skill and I give myself XP to a certain skill it gives me nonsensical amounts and not the amount I set for example instead of 40,000 it gives me 2456463215. It doesn't matter what skill I have set skill_xp_multiplier to it does this for all skills. The size of the multiplier also doesn't matter much as I tested it my multiplayer was 1.25.

To Reproduce

1. Make an item where you have skill_xp_multiplier on any skill for example via talismans or ecoitems.
2. Reset your skills
3. Type twice the command /ecoskills give (your name) 40000 (some skill)
