Disintegration
Disintegration (dx) is a glitch-based mechanic that causes elements to disappear instantly when certain conditions occur.
Level elements exist on a grid. Moving elements use reservations to properly express the transition between tiles. These reservations are removed when the transition is complete. However this cleanup does not always verify if the reservation still exists. If the reservation tile is somehow removed and another element enters that tile - it can be unexpectedly deleted.
Explosion clouds are immune to disintegration.
Originally this mechanic was referred to as "disappear trick". Gregot proposed a name change to something less mundane to reduce the possibility of confusing the trick with potential bugs in new elements.
There are multiple tricks that use this mechanic.
