Haha its actually the museum is too small rather than the diplodocus being too big. But to make the museum bigger would've caused a bunch of issues so we had to leave it like that (for now).
In the main game you'll have a much bigger area to exhibit your bigger dinosaurs.
I get that, but like, I just want to rotate it 180 degrees, which SHOULD fit, but I have to turn it 90 degrees first. It would be nice if you could ‘rotate’ it when placing even if it wont fit if you do that,(IE-keeping it in ‘red’ mode while you preview the rotation) or something.
