My friend has showed me a glitch related to relics; basically, he was able to send me a high number of relics, when he clearly didn't have that many (he has barely been online).
So, I don't really know how it works, but if you can find trade partners that can perform this glitch, you could basically trade infinite relics and help everyone complete the event in a matter of seconds.
This is obviously quite unfair for people that have been working hard to fish the relics, or to find someone with the relics they need, and I just hope admins can find the source of it and patch it ASAP.

A friend told me how it works and requested I tell an admin on their behalf, and I've reported it to Pikashu I believe (because posting it publicly would've caused all sorts of issues). But yeah, this is complete and total usebug and it needs to be resolved asap.
