Number 8 under improvements and game hanging on startup message windows is a splash screen failing to load its graphic, probably the one about purchasing old LE buildings for a limited time. Tapping where the action button is or where the X is will cause the game to proceed.
Add:
PvP: iOS - Along with Bugs #8 - some iOS accounts are completely unable to attack in PvP. The game hangs on the screen where the doors come together and never completes the attack cycle. The only way to proceed is to force close the app and relaunch it. It may be a once in a while issue for some, but for a few people on my team it's every time and PvP has been broken entirely for them since 5.0 was released.
Raid Boss: Global - Sometimes the server doesn't seem to recognize that a boss has been completed and forces the 2hr time clock to run all the way down before proceeding. It doesn't show up any longer under the "select boss" tab, and the summon button for that level boss remains missing from the summon tab. After the 2 hour clock runs out, the completion splash screen appears, and the summon button for that level reappears.
WD Leaderboard: Global - The points and positions shown on the leaderboard before and after the final battle are not consistent. In our final battle we faced a team who was ranked 3 spots below us going in, and both of us fought hard. We won the battle with more points than them, yet somehow they finished the event ranked 3 spots above us even though they were ranked below us before the final battle and we added more points to the board than they did. It's as though the leaderboard credited them with our points and us with theirs.
Building Construction: iOS - New building construction sometimes continues to appear as still being under construction even though it's complete, even with restarting the app. Tapping on the building shows it as level 1 with xx:xx time remaining until collection and has the upgrade button, and tapping the upgrade button and starting a new upgrade causes it to show correctly. Other than doing an upgrade, the only way to get it to appear correctly is to wait until it's ready to collect, then collecting it will update the graphic to appear correctly.
Equipment Inventory: Global - was this on the list? We need a way to see in our inventory how many of each equipment piece we have for our army.
Edit 1:
Raiding: iOS (global?) when raiding another player, veiwing their profile showed they have 6.3B defense, but when actually raiding a building the results show they have only 4.1B defense. Yes, composites factory was in tact.
