Not intended but it is more of a DQ's config bug.
Bonuses for DQs were not properly set up yet, I'll have to adjust them.

For now I'll just leave a note for a future me:

• Disable bonuses that rely on tower availability on DQs which have cores with tower on/off effect. One of such levels is DQ8

Have to mention that bringing different abilities can also affect the result in 6.6, if the sequence contains reducing ability energy cost.
Moreover, there may be some more sick and innovating ways to exploit it such as entering 6.6 with crusher never unlocked by some ways, in order to find more possibilities of bonus sequence.

To prevent exploits, forcing every tower to be available on 6.6 as base effects would be a decent idea.

Gauss and Crusher are forcefully enabled on 6.6
DQs will be adjusted later manually

DQ3 must be edited to (remove min boss wave 30 to make SummonLootBoss work)
