1. Consume your grenade with Tessellation to activate Property: Irreducible. 2. Wait for the 'Ether Siphon' buff to activate, then wait for the buff to expire. Tessellation then displays an empty mag, and cannot be reloaded nor fired. Only fix is to either change to a different energy weapon or die. Bug occurs even when: Switching weapons, changing to a different primary or heavy weapon, stowing Tessellation before/during Ether Siphon, activating Property: Irreducible during Ether Siphon. Swapping any piece of armor or armor mod will break Tessellation regardless of buff status. Holsters also have no effect, although the holster will continuously proc (Holster SFX every 2.5 seconds) while Tessellation is stowed with Property: Irreducible active, regardless of magazine count when stowed. The same bug occurs when using Revision Zero's sniper mode in 4-burst (2-burst currently doesn't work). Simply swap to the sniper mode and wait for Ether Siphon to expire. The sniper mag is emptied, although the gun is still able to be reloaded and fired after. Other 'dual-mag' exotics (I tried QSS, Grand Overture, Vex Mythoclast, and Symmetry) function normally.
