Void Def, Host migration bug, Rewards wiped.

[LoveLost]

Just got out of a 15-wave void def. (Taranis) Hosting was fine until the final wave(15) , then there was a massive lag spike that worsened the longer the wave went on, it resulted in being unable to move/revive and host disconnecting, causing a migration, when loading back in from migration the usual "continue? or extract?" menu came up but the completed tiers of rewards (5 and 10) as well as the final reward tier reached (15) all changed to awarding nothing saying something to the effect of "unavailable due to inactivity" didn't get time to screenshot it because the time it occured in was so short. One second it was fine, the next lag was rapidly increasing, then bam, no rewards for any of the completed tiers.
