mbot 1.12b bug bolts

someone playing with crossbow have bug buying bolts using this bot?
here mbot only buy 250 bolts and I put to buy 5000
if you put to buy 251 bolts it do not buy anything !!!
Is locked at 250, for example:
if you have 300 bolts in inventory and set to buy 600 (bot see 600-300 = 300 you need to buy and 300 is more than 250 then bot not work !!!

anyone know how to fix this?

#wrong section -> Use Ask The Expert Next Time
Can you buy more than 250 bolts normally *w/o the bot* ?

yes, manually I buy more than 250 without errors

I am using serverfiles V188 and database cap 120 d13
