Abyss tablet mod - additional rares are spawned doesnt seem to work properly

Hello, i tested a lot abysses with and without this mod, the conclusion is that the mod doesnt work correctly:
- without it rares spawn from abyss only when they are effected by the cracks, which is correct
- with the tablet i can see additional rares that were not in the crack spawn 1-2 times out of 10 and they are not even the correct number

My guess is that something went wrong after you change/fix something on the 0.4b patch when too many additional rares were spawning.
