Edit: Can I keep playing or do I need to log out?
We had a small panic attack here,
is marketplace corrupting items?!. Turned out things are pretty great, the bug is very very minor and not as scary at all. You can keep playing AND you can even take it out of the storage now. The minor bugfix is going to be applied anytime now.
Do you mind if I explain to other players what happened? If that's not OK, I'll PM you.
sturdy engine at 4m cooldown time instead of 4.5 I don't see the point
There's actually a pretty good point there, although I shouldn't really tell you what it is. In any case, if you don't think those 30seconds are worth the satoshi, simply don't buy it. On the other hand, the cost/blueprint itself will likely be changed in the future, so there's that.
