3 of the weapons seem to be broken. The Bloodstorm primary fire is not functional, it will behave as if its firing but fire no projectiles and do no damage. 2 more weapons are apparently missing, appearing as generic item blocks. There is also an issue with the bottom opening of the original room when going between the second to last upgrade to the last upgrade of the ship. It will show an opening when none exists, this is possibly due to me putting platforms there between upgrades, but either way should look in to it.
