Rift mats are decaying while beacon still open and rift mobs present

[Galatyn 303]

Just cleared a beacon and saw this plant with high damage.  This is becoming very common.  Please change before all mats disappear.

 

[18:26:55] This rare plant doesn't seem indigineous to the area. Ql: 74.8051, Dam: 89.2598.

Indeed. We even cleared a strong beacon on a mountain top the other day, and found no mats around. Zero. We also knew a beacon where there was wood a couple days ago, went there, the beacon was still active (with mobs, nobody beat them yet) but now there weren't any more plants. They must have decayed away.

 

Mats should start to decay after the beacon is closed, not as long as the beacon still has its defenders.
