I have submitted a ticket (#711450) in regards to this issue and it was suggested that I make a post about it here also.
There are currently two guild consumables that have been fully researched that I, or any other person with the correct permissions, cannot activate. Contract Asuran Outsourcing was built some time in late April or early May of this year, I cannot remember the exact date, and Guild World Event was researched this past Saturday June 29th.
The guild is on Tarnished Coast and has been since early November 2012. No-one was guested on any other server when queuing or rushing through these upgrades. I bring this up as I was told to make sure that I was on the server that these upgrades were made on. I have only guested once or twice away from TC since the megaserver was introduced. We have built many other guild buffs and consumables since the megaserver update and most of them we have had no problems with, it is just those two that I mentioned earlier.
I have made two in-game bug reports about this — one a few days after Contract Asuran Outsourcing was completed and unable to be activated by anyone with the correct permissions, and another one just recently as requested by the GM who replied to my email.
I understand that bugs can take time to be addressed, investigated, and fixed. Now that we have these two upgrades that we cannot use I am hoping that it will be eventually fixed.
