I just wondered if using a console command will disable further achievements or lead to any other side effects?
The wiki only states that using a command will "impair your Subnautica experience" which is not quite helpful in this case.
The wiki says that it might impair your Subnautica experience because of the higher possibility to encounter bugs while using (or abusing) the console.
As far as I know, there is no achievement block, since you're using the debug console.
Also, I bet that there's a command to unlock achievements, but I might be wrong
