Literally my only complaint with the game is that a completely voluntary decision to view an ad occasionally has an unmutable ad. DivineGames, I really love what this game was and it's only gotten better.
@cassavaftw There actually is a wiki. This page should answer your question about unlocking the production upgrades: http://realm-grinder.wikia.com/wiki/Upgrades
@DivineGames What is the best way to report issues to you? Also thank you so much for continuing to improve what is quickly becoming my favorite idle game ever. :)
Either a PM or the Bug Report feature is the best way to report a technical issue such as saving problems or gray screens (still working on those), or minor bugs like a tooltip typo. For suggestions, balancing issues or gameplay related questions though, it would be better if you write them in a public area - this comment board works just fine - so that other players may add feedback or perhaps solve your problem before we even get to it.
" 1) Two upgrades that reduce the mana regen loss from auto casting first to only 25%, then no loss."
These upgrades exist, and can be unlocked at 2 million and 6 million total mana spent. I have the one for 2 million mana and am working on the 6 million one. Obviously angels help a LOT.
With regard to gray screens, I've been able to cause them consistently by clicking on a button that is grayed out. Frequently requesting to build a building, buy an upgrade, or cast a spell that I don't have the resources for causes either a gray screen (with only the buttons I was clicking visible) or a freeze of the game followed by a gray screen when I stop clicking.
