I've talked with the creators of the Elemental Ark mod where some of their effects seemed to have been blown way out of proportion. Turns out that it may be an issue with this mod instead. The Tarrasque model may have its "BuffSocketCenterDynamic" turned up too high. I can't say this is the only creature with such a problem, but it's the only one I have a picture of atm.
