When i use mod Beltlayer https://mods.factorio.com/mod/beltlayer CTRL+B and goes to do underground belts it causes Spidertron to disappear.
probaly same with pipelayer
Thanks for the report. Does the spidertron come back when you re-enter the 'normal' world? If not you can use /create-spidertron playername to recreate it (though that means that it is a bug that I should fix).
Sorry for late responce.
It does not come back when i re-enter "normal" world that how i noticed it disappearing. but have not taught of /create-spidertron
