Dragon Stone - no base defense bonus
I have/had the dragon stone, base defense bonus, on (during 3 free hours) and paragon level 5 on... I went to add improvements and for the Red Dragon (or any of the other ones) it only showed the +3% for Paragon level 5 it did not show the active plus 9 pct for Dragon Stone Castle Defense Bonus.
So I added forifications instead until you get it working correctly.
Remind you that the Red Dragon is a Castle Guard by your own description (and I bet you two things - 1 - unit defense does not show up either and - 2 - whatever bugs you have here are the same in Soldiers Inc. since programmers cut/paste). Thank you for fixing this ASAP.
