Thanks, sorry it wasn't 1 row per se. 20 grass tiles were removed in no particular order. So it went from 60 --> 40 grass tiles, which is basically a guild house farm equivalent, except that you have to do twice the work, and spend twice on bombs when compared to the guild house farm with a spar arena.

I just hope that the people who still have the original castle aren't forced to update their house, especially when I just bought the mechanisms. Really wasn't expecting them to nerf it, as it didn't seem to need one. You could still make more with a guild house vs original castle. Only preferred castle, because it was pretty much made for 2p mounts.
