^Did you gain a level after the maint ended? In so, you'd still retain that +10 unit cost, otherwise, it reverts back to its original unit cost.

At this juncture, I'm thinking they never intended to increase the unit cost, ergo, it was a mishap on their part. But, assuming in arguendo that they did, it wouldn't make any sense as it was never part of their patch notes. Furthermore, granting that they did intend it, I must be ecountering a bug of sorts.

All in all, no official statement has been said, all these are just plain conjectures.
