sorry to bother, i didnt want to post bug report for Merchant prince's folly.
on my first run, only did for questline, we killed t-rex, i was bit slow and love exploring, when i get to chest to claim my loots, t-rex respawn near the end where i open the chest, it didnt let me collect and i was forced to kill, took me awhile solo, and went to chest and collect since my bag were just about overflow, and leave asap.
few weeks later, after i got more expert on layout, this is report i want to let you know asap. i just sensed one pug non guilded group stayed after looting the chest rewards, they camp respawning t-rex for higher grade drops or xp grind, i dont know.
this remind me of old water seed quest in ebon down's seed gathering with endless crabs respawning and i reported about 2 years ago and they fixed them as 1 time spawn.
i am surprised a new respawn bug is back. i feel it would be exploit, i discuss with my guild leaders that not recommended to farm. thanks
