While in tactical combat I cast a spell intended for elementals. However, none of the enemy units were elementals. I tried several things to cancel the spell; r-clk, <esc>, <Enter>, I had to kill the program.
Is there a problem when researching Advanced Agriculture? Once I have researched that tech it still shows up in the tree as though I haven't researched it. Also, I don't see the effect of the tech.
