so...I was playing zigurat today, and oddly found that after I just purchased..(well what I thought was 3 flag locks)..

a bit later i looked down to use one of locks and I found i had 4 in my inventory in particualar:

3 Ports/3Locks/1lock in that order.

well I figured i would use the single lock on the right, and free up the slot..i locked the flag.

next thing I knew..I the slot still had lock a in it (I couldn't use it..due to cool down)..

anyways I found that I could reuse that slot over and over but the lock wasn't getting remove from my inventory...I guess its bug..but I wonder if there is an exploit for this..becuase I swear once in awhile I end up in a game where the opponent is locking everything left and right...(from the start of the game) and based on past experience..I can't figure out how the hell they have so much money to fire off locks they way they r..and still maintain their creeps/citadel etc.. which makes me ask the question....could they have infinite locks? like I had with the game I just played today..

anyone else experience something similar?

is this by chance a known issue? have u taken advantage of this in the past? (I told my allies about it....naturally they just thought it was cool..lol)
