Workers clean the fish tanks in 3 different time zones with the watercleaners.

1. At first you should redistribute this job for each new worker (little menu right side/go on "jobs"-menu).

2. Each watercleaner has 3 time zones for water cleaning, you should set this for each watercleaner seperatly. (little menu right side/ go on "tank"-menu)

3. Place a bank or another seatplace close beside the water cleaner (so the guys don't run away).

Every time, if I install the usermade expansion: "new sky", at the same time my 3D visitor-mode malfunctioned! Always the visitor route forwards and backwards only, whether with mouse or keyboard.
I don't understand, where is the connection between guest-mode route (for/back) and the sky coding!

Has anyone the same problem or does anyone know, where I can find the mistake?

I've tried penning the maintenance workers next to the filters and they still don't clean them. I've adjusted the timers for the water filters and that doesn't work either. The absolutely will not clean them for me. Maybe I've got some hack that is messing with their coding, I don't know. I finally just gave up and clean them myself and don't bother to hire any maintenance workers.

Alpharaptor,

If you hold the shift key down while you use the terrain tool it will work under the fences just fine.

Also the space requirements are really annoying. I know the bigger the better in general, but in reality many animals are kept happily in small cages with no issues (sometimes it's not the space that matters, but how it is used). I should get off my lazy butt and figure out how to edit space requirements...it's eazy I hear?
