Hi! I posted this in the other bug thread and just realized the issue is related to saving and loading, so I wanted to start a new thread instead. When I played through mission 3 in one shot it worked just fine. When I saved and loaded partway through, on picking up the computer from the shipwreck it properly displays the pickup message ("Yaaaay, ...") then pops up this error:

Error while running event level::on_tick (ID 0)

stack traceback:

Hi,
Thanks for the report.
I tried and I got the same error. I did not find the way to correct it for the moment.

One way to avoid this is to not save as you said.
As soon as I find a solution, I'll post a patch.

I have uploaded the version 1.0.2 that should correct the problem.
