Can't do the Reliquary on Alt?
Try going in with someone else who hasn’t done it yet. I went to help a friend who had the no-progressing bug and got a second golem on my main. If he can get two “uniques” maybe an alt of yours can get one.
Certainly not ideal.
Please Anet, either make the golem account bound, or allow us to repeat the instance with our alts. I prefer the first option because I hate character bound items. It’s a mess in the bank when you have 8 alts.
