Modpack will not start,

So dungeons dragons and spaceshuttles will not load ive gotten an actual crashlog where it looks like nothing went wrong and then an actual crash where no log can be created. heres the log it could create. https://mclo.gs/Xn71XLo
So looking around ive read a response to these kinds of posts, heres the response "We always try to get the best possible balance between our limited resources (since we are free and we don't want to change that) and the best performance. Especially for mod-packs, this is really hard to achieve. We test the mod-packs in our system to ensure that they are at least starting and that basic playing is possible. Because mod-packs are always a bit different and the load on our host systems is also always different we cannot guarantee anything here. But we decided to still offer mod-packs on our platform because we want to offer as many options to customise your server as possible and most of the mod-packs are pretty playable most of the time."
ive read another post saying this same modpack wasnt working before in may so the pack was removed but re added, i presume re added because it runs now, but it doesn't so how can you say its checked.
