Detailed description of the problem It looks like when leveling up (I'm leveling a wizard, 8 to 11) it is loading all of the spells into memory. It loads them slowly one by one down the list. When it gets to about level 4, it throws an SBOX_FATAL_MEMORY_EXCEEDED error. Minimum number of steps to reproduce the problem Create a level 11 Wizard using charmancer.
