Another thing I found is that the temporary large engine confuses AI that attempt to place it in small ships where they can only put 1 and it doesn't leave space for other components.
I'm removing the temp filler now. And races will get large engines along with the big ships, so that should at least partially sove the problem.
I wish there were engine mounts that worked somehow like weapon mounts increasin their performance and with size limits.
