The behavior of push and the enforcement of its max value has changed from the 1.22 sim release to 1.23 in a drastic, and negative way.
While previously, any number too high on push simply resulted in the push's power moved down to max, right now any number that goes above the max strength of 2147483647 (max integer) results in the push being nullified, or close to nullified.
This severely impacts alot of non-grief products like movelocks and flight assists, where the creator simply set a huge value to get the boost, and relied on the sim capping the push power down to its maximum.
This expecially hits older products and products where the maintainer/creator is not in SL regularly.
This strikes me as bug, and I suggest simply going back to the old behavor of lowering push levels to the defined max if the number is too high.
