Hi, i am trying to multilog with woodcutting bots using perfect chopper. This script uses a large amount of memory and running 3 of them at the same time uses even more. I tried altering the memory allocation for OSBot but it wouldn't open with half of the numbers i inputted. For example, if i type in 800 in the memory allocation it works but if i type in 2048 it doesn't work. How do I fix this and give OSBot more memory to run?
