Necro Summoning Zombies bug?

I was able to summon 6 zombies before the server disconnected me. I have 2 gems allowing me to summon 6. I logged back on after 1 minute... and when I tried to summon I was only able to summon 3?

I notice that the gem now only allow me to summon 1 per gem. I did not change my passive nor anything.

What is going on? Did my gems get resetted or something but it is still level 4? but even then it shouldn't cause any problems?

Someone help please thanks.

I was wondering about the zoning where I have 3 zombies up and when I zone they disappear, and I start all over again...it is a pita but if that's how it's designed...so be it. BUT if it wasn't designed like this please help a guy out.

The summon zombie is hit and miss with how many you get due to a bug allowing you to use more gems to get more zombies...this will be fixed in 0.9.12 i think they said so no more multi gem use.

As for zoning in to an area and all the zombies disappearing i don't think its classed as a bug but it is something they are going to change.
