After level 40, the game will lag to death. Seriously lag to death. Towers will stop animating, you can only see one line of say "fire", or one line of "arrow" Spec: 32 GB Ram, i7 12k, Nvidia RTX 3060

levels at 160, wipe, actually any one over 30 wipe, i have played enough hours to know those people never ever played the game and used some tool to fake their scores, do something about the leaderboards and cheaters or simply remove them, i have played long enough now to know not even the developers can make it to 30 on any map aside from it being luck of the draw on every map, what lands you get, the weekly challenge maps, no way a person can get over 30, not possible, so leaderboards are a literal joke,...

I cannot seem to figure out what wave or map the flying units come? Can someone help me out?!

Specifically rivers. Why can I not place a hex on most rivers. I click the hex button and the tile behind most rivers is grayed out. Why? The tutorial says to loop rivers to stop boats, but....how can I do that if I can't even place tiles behind them?

The tutorial gave me a tile without a road to put on a hex that required a road.
