As mentioned in the TTS Communication found here, we are testing a series of tentative fixes for collision on the TTS.

The results have been favorable, so we are planning to deploy 3.1.1 next week to PC that will include the adjustments made to how collision is handled in game. This will have the benefit of reducing the following instances of collision exploiting: player-to-player collision, player-to-object collision, and player/shield collision.
