Rafinery event bug

I sow that some times kanturu core gate whont open , it looks like u can open it all u need is ring of nightmares well i put that ring on and gate still says moonstone pendant bla bla , and its not the w8 period like i know those 10 min it just stays that way, im staying right now fore like 25 min and nothing, usual it works but i happends like i sayd to in a while or so

 

donno...try using a not damaged ring... with max durability

 

now it works its that countdown and then another 10 min, but i still think is bugg couse i w8 like 30 min and nothing happend till now
