Hi, there is no limit on items, but I think this is what happened:
- first game version: "blueprint" was a flag that was set when in front of blue sensor
- second game version (from yesterday): "blueprint" is an object that you get when in front of blue sensor
the issue is that if you started the game in first version, then continued with the same save in second version, there was an error when getting "blueprint" object. This should be solved now and we will take that into account if we have any other updates, sorry for the annoyance and many thanks for the feeback 😊
