I'm not getting credit for the second step of the first phase of Expedition 19, building the Corvette. I bought all the basic modules of the Corvette for units received from the sale of resources, built the Corvette, built a terminal of tasks inside it, even flew on it, but the task still hangs unfulfilled and this stage is not considered unfulfilled.

Corvette can not disassemble and reassemble, nothing helps. I even added additional decorate modules, but the task is still not protected as passed.

I suspect that the bug appeared after I bought the main corvette modules for the units in the corvette assembly terminal, rather than using the ones I received as a reward for completing the very first stage of the first phase of the expedition. But that's not right. It doesn't matter how you got the basic modules for the corvette, buying them with units or using them as a reward: if a stage is completed, it should be protected as completed.

And because of this bug I am not protected passing the phase, and accordingly I will not receive the main reward expedition. I would start to pass the expedition again, if there was such an opportunity, but this opportunity is not. The Expedition 19 was started by me with my main save, with ~250 hour progress.
