same problem on RZ here. recons are left in limbo.. 63 troops in tracking no report nor do they ever return home. clan mate sent me in game mail as a test, did not reach me. another clan mate sent me credits with caravans, never showed the caravans incoming or the resources. only report that i have gotten these past few days is when i sent troops as a test to lvl 21 campaign defensive infest, 1st time 600+ cyberdogs and then changed to private browsing on my opera and got the report almost immediately, 2nd time i did not change to private browsing and it took hours to get the report for 14 cyborgs in the same infest.
if your policy in a situation like this is to tell customers that their troops died "normally" and will not be compensated/made whole, you are making a mistake that will cost you money.
EDIT: seems whatever you did last night fixed at least the report problem and troops no longer stuck in tracking.
