RoG mole problem.

[erictred1]

                      Hi guys I don't know if this has been posted before but in my 700 day plus game as Wilson I made a mole farm. In the beginning everything was fine I made a large walled in enclosure and added about 50 or so moles into it. Now the moles I gather were from the south of my base and thought nothing of it as I soon noticed that the moles were respawning at the same place I took them from which I thought was a natural  game mechanic.

                                      However after a while at 1 point in the game returning to my base from the north my system started to lag very badly which was weird to me because I have a pretty good computer. Then I saw the problem there must have been over 75-100 moles at the previous spot I farmed them from. So I basically culled them to 0 population cause I didn't need any more moles anyway but I was a serious pain in the butt to get rid of them all.

                  Now I read up alittle on the web to see if anyone else had the same problem as me but couldn't find any solid matches to my problem. I use no mods and know nothing about duping items or mobs. Is this a bug cause ever 5-7 days I have to go back and kill them all which is getting to be an extra unwanted chore althou if I keep an eye on them and kill them quick there are not as many ranging fron 5-30ish but its constant and a pain. Any idea's how to solve this or is my game bugged I hate to leave it cause I'm ready to do a major cave push come autumn and don't want to come out of cave 40 days later ( playing on very long seasons) and have 1000's of moles to deal with. So any clues as of to what started this guys or gals any help would be greatly appreciated and TY in advance !
