Started a new map in 0.18, on placing my first assembler getting the below error:

Error while running event Bottleneck::on_built_entity (ID 6)
real number expected got nil.
stack traceback:
Bottleneck/control.lua:83: in function 'new_signal'
Bottleneck/control.lua:110: in function <Bottleneck/control.lua:99>
stack traceback:
[C]: in function 'newindex'
__Bottleneck/control.lua:83: in function 'new_signal'
Bottleneck/control.lua:110: in function <Bottleneck/control.lua:99>

Looks Like I got the same thing.
Error while running event Bottleneck::on_robot_built_entity (ID 14)
real number expected got nil.
... (The rest of my error log shows the same as above.)
Reverting to previous version works fine.

Should be fixed by 0.11.1. Can you confirm?

Thanks

Hey trold, can confirm no more error for me. Thanks
