If you have not noticed the quick fix Pocus posted in the "improve PON" section of this forum, there is one, and it appears to have fixed the main problems with RC2.
The lag problems with the B and F4 screens are gone, and Pocus wrote that he fixed the immortal garrison bug as well. I am at peace and have not had a chance to test out the garrison bug, but I believe Pocus has fixed it.
Pocus is planning to do more once To End All Wars is done, but what he has already done is a great improvement
Now I am enjoying the game again, and it is grand!
Thank you, Pocus!
