Bug: Free Epic Fight Missing

UPDATE Hey, hey. It seems you can fix it by exiting the Invasion menu, then re-re-entering. My free Epic Battle was made available again.

Platform, device version and operating system:

Gems of War on PC

What you were expecting to happen, and what actually happened:

I lost a battle in this week’s Invasion event, and Luther popped up and prompted me to try out an Epic Fight for free. I expected a free Epic Fight but was not given one.

The Epic Fight screen correctly displayed 0 sigil costs for Epic, Legendary and Mythical Battles. When I picked one, it took me back to the Invasion screen and displayed an increased sigil cost for my next battle. It was not 1 sigil as I expected.

Steps to make it happen again
It’s impossible to for me to replicate it, because it only pops up the first time you lose an event battle after 4.4. However, I saw at least 1 other person who post about this. I just don’t remember where.
