Could we have space age be optional for this mod? I would like to be able to use this in other mod packs that don't include space age.

Ok, I removed the dependency on space age

Befor is work fine, and now, i ave this error, i use it with space age, and is very nice ... befor

Le mod Auto-Switch Techs (1.1.1) a engendré une erreur non récupérable.
Merci d'informer l'auteur de cette erreur.

Error while running event AutoSwitchTechs::on_nth_tick(600)
Unknown virtual-signal name: AutoTechSwitch-science-alert
stack traceback:
[C]: in function 'add_custom_alert'
AutoSwitchTechs/control.lua:87: in function 'alertForce'

Thanks for reporting, should be fixed now
(problem was AutoTechSwitch instead of AutoSwitchTechs)

It works again, it's great
there are no more alerts, but it doesn't matter, it does the job perfectly
I love it
thank you very much for your work, it's great
