Incubators in alva temple

Hello,

When incubators pop in alva temple in map rewards don't drop even when i leave incursion. Is this intended or is it just a bug?(rewards from incubators were essences on both ocasions)

Regards,
Lost Exile

I think its a "feature", but it might get corrected eventually

I've had it happen on an elder guardian and also lost the items that way because elder switches arenas in between phases and there is no way to go back to the old arena

What is left on the ground in temple stays in temple...
