Trooper Event Challenges have Disappeared

Self explanatory. On IOS. All challenges that award warfare soul frags have disappeared.

They did drop from 11 days to complete to 4.... but they are still there for me. (All mine are done though, maybe that matters?)

[Wyphy]

Still show, but moved to the bottom of the list. Still says 4 days.

My final challenge (echo) has stopped at 261 and no longer counts cases of echo. It sure would be nice to get those last couple of souls
