Loot chests levels

I recently started playing CE again I have a mod that allows for leveling past 60. I’m level 91 and just killed my first boss (taking my time exploring, building and crafting.) I got a skeleton key but couldn’t open the loot box. I’m playing in single player mode. Any suggestions ?

Tell the person who made the mod to fix it? I haven’t looked, but if the “open chest” check is a simple “if (player.level == 60)” then obviously it’ll fail for levels > 60. It seems an obvious thing to include in one’s mod, but it’s easy to overlook things like that.

Thank you
