Tunnel exits during infected camps period

Hi

So we are playing on Tib 62. MenInTights alliance. We have noticed since the infected challange started that our tunnel exits accorss the alliance stopped automatically spawning a replecment OP when an OP is killed.

All the usual criteria is met. 5 players minimum around the tunnel at the correct distance and army levels. The tunnels were working fine until the minute the infected challange started.

Really i just want to know is this limited to Tib 62 or is it all servers? Also is this a glitch or is it by design to encorage people to farm the infected instead of the tunnels? I do not remember this happening on previous servers.

The Infected although great for getting RT are hard to kill. Most would really like to be farming tunnels as well as the infected at the same time or we build up a lot of unspent CP.
