Random Error spams console

[Demo]

Hi,

so randomly every 15 Minutes or so this "error" is written into the server console, however it has no negative effect on server:

!! ERROR: bad input/output link:
!! logic_timer(horsetimer,RefireTime) doesn't match type from logic_relay(horseracerelay)
!! ERROR: bad input/output link:
!! logic_timer(horsetimer,RefireTime) doesn't match type from logic_relay(horseracerelay)
!! ERROR: bad input/output link:
!! logic_timer(horsetimer,RefireTime) doesn't match type from logic_relay(horseracerelay)
!! ERROR: bad input/output link:
!! logic_timer(horsetimer,RefireTime) doesn't match type from logic_relay(horseracerelay)
!! ERROR: bad input/output link:
!! logic_timer(horsetimer,RefireTime) doesn't match type from logic_relay(horseracerelay)

Any idea how to get rid of it?

Thanks in advance!

Remove the entity that causes the message on server spawn or whatever.

The map itself has bad or broken IO (map IO being things like pressing a button should open a door, etc)
