@Alderon75 Hi,
I just wanted to confirm that the studio is aware and working on a resolution for the issue with the door in the raids. Thanks for reporting it.
In regards to the cooldown for devour, can you be a bit more specific on what you were encountering with it? Is it related what had been reported here: https://forums.galaxy-of-heroes.starwars.ea.com/discussion/56575/rancor-stage-2-devouring-every-2-rounds
As for the mods, none of them should have disappeared. What we did change was that they are no longer guaranteed to drop, instead they are chance based, similar to character shards to avoid over flooding them.
If there are still any items missing, please report them to our team: http://help.ea.com/en/article/how-to-contact-support-for-star-wars-galaxy-of-heroes/
As for updating the mods, they are indeed quite costly if you are updating the high ranked ones. I would suggest instead of maxing a single one to update them steadily for all your main characters, credits permitting.
We have already increased the payout for completing nodes in Galactic War and recently implemented new challenges that should help with the credit income.
Cheers,
Nils
