It doesn’t sound like a system failure. If you were away 2-3 days you would have missed the pop-up in game that would notify you. It happens, this is why OPs are usually held by large guilds with many active players. Even a non-guildie of the same faction could have noticed the attack if they walked into the OP zone.
I’m not sure an Izam message would be more effective than the pop-up. Many would also complain that Izam mail can be checked irl, so that violates the RP component of OP wars. You can set the time of a defense, but not the day.
My advice, enjoy the q50 mats that you received, although you’ll probably have difficulty giving them away- and hope for more development in OP War games like what is being developed in Nexus.
