Bought the game this weekend and have the same issue on PS4.
Bought some shards and could use them once. After logging out and back into the game a few hours later I just see 3 question marks instead.

My internet connection is always working and I always play my games online... I never deactivate this.
I checked everything and confirm to you that this is still the case. Also my PSN updates are done as soon as they are released the first time I connect on my console.

1. can't connect to multiplayer for almost 2 weeks now

2. can't connect to leaderboards

on 1 and 2 there's a pop-up box saying infinitely connecting....

3. my trophies don't pop-up anymore after they did the first couple of days, and i'm absolutely sure i fulfilled the requirements. for instance reach 50 and 100 stars on the campaign map. I have over 110 stars on my sorceress and no trophies. there are other trophies as well, but these are the most basic2.

4. When i play endless mode with my sorceress on Darkmoor (the first map) the game closes with a blue error screen between levl 25-30. This happened to me on 3 different occasions.

The psn error code tells me to ensure i have the latest game version and psn software. Both are the case. 

5. Every now and then when you load a map i'm unable to upgrade my traps after bying the trap. Annoying but when i press restart the map it's working again. Nevertheless this should not happen. I always play online with no internet issues in any other game.  My PSN name is Worldtour1966.

When i read on internet that xbox had similar problems 3 years ago, it really makes me wonder why the staff at neocoregames didn't test this game properly especially on these issues.

I hope this will be fixed in the shortest time possible and with the highest emergency.

Greetings.

I also have the same issues since day 1 I bought the game...
As for point 5: Yesterday I had to restart 3 times before it worked... Only had this case once though. Usually 1 restart is enough...

Same thing going on for me. Bought 500 shards first day, and was able to purchase 1 special offer item. Since then, nothing. Cannot connect to server for mp, shard inventory shows ??? and unable to purchase any other special offer items.

Is this going to get fixed? If not I would like my 9.99 refunded please.

Figured I would help support the game buying the shards, but in hindsight doesnt seem like that was a good idea.
