I've been struggling with some of the contents of the cells unfortunately. Such as the water storage cell, or the Death Bringer cell. Some of the stuff has been spawned in using commands, and while I can make an invincible wolf and tame it, I have no idea what else the Death Bringers have in the way of abilities. The problem comes with seeing all the objects in the cells though, as it took me a little bit to figure out that the water storage cell was a bunch of ice with a redstone lamp in it. I wish there were images for all of the cells, at this point it might be easier just to get a downgraded version of the mod-pack, if that is what's causing this.
Somewhere earlier in this forum there was some kind of fix talked about. A file that you'd put in your map folder. The modpack's author had posted that there was a bug with older maps, and then uploaded a file to a google drive, but that file has been removed, unfortunately.
I'm going to check out the newer map, and see if that changes anything. With any luck, I should at least be able to play Blast Off!. It should be about the same, just a different map right?
