I don't think the internal error messages or the lag in the game is a computer problem. I recently bought a brand new gaming computer and the game was working fine until the events started. Which makes me think it may be the servers are overloaded. They just can't handle the volume of elves and humans playing the game at the same time.
A tech was told me the game developers need to fix the memory leak. When you visit someone, the game will temporarily store that city in your PC's memory, then you visit another city and another. Each time you visit someone's city, the game keeps storing the data from all the cities you've just visited instead of just storing the data from the current city you're visiting. It ruins the gaming experience to have to stop several times to refresh and/or clear the cache. If that's what is happening, that is a strain on my computer's brain.
