I beat I think two waves of robots, and now the mechanist just keeps sending the electric tesla shocks, fuel tanks and frag mines, electric tesla shocks, fuel tanks and frag mines, alternating in a loop over and over again endlessly. thanks in advance for any help anyone can offer.

Spoilers forum please

aw, sh.... sorry about that, my mistake. Don't see an option to delete or move the post, so hopefully a mod sees it and moves it to that forum.

Reloading worked for me.

If you need technical support or suspect a bug, please post in the proper support section. Since you didn't state what platform you're on I can't move this one.
