To expand on this: tick 1: at 48,24, move east to 49,24 tick 2: at 0,24, move east to 1,24 so you basically move 3 squares in 2 ticks... which makes me think that when I'm estimating distance to somewhere, instead of doing #rooms * 50, I should do #rooms * 49

FWIW I've dealt with that by checking for error codes. If you try to send from an inactive link, it tells you RCL not enough or whatever that error is. If you try to send to an inactive link, it tells you invalid target. As the cost of isActive() is significant, I never actually call it.  I just look at the error codes and mark them as internally inactive the first time I get an error trying to use one.  Worst case you have 1 error returned when you try to do something, and in any case you never waste extra CPU polling isActive.

This bug is still present in the simulation room. Whenever I zoom in on a container it will show a construction site underneath. Changing to a different room is impossible because it will reset the sim room. It also happened that containers were never finished, even though the creep.build() returned 0.

You rocks !Thank you !

Prime's solution is the cleanest imho.

Fixed.
