I became a quick diehard fan of this Awesome game instantly and had good luck with lunchboxes, got 4 legendary dwellers( Had them trained for level 10 stats) and 3 legendary weapons ( rocket launcher had 23 hit points). But now, i cannot access my vault 470 as game crushes after the loading screen repeatedly. I cleared cache and played offline, still force closes. I am anxious to reinstall, as i fear that i will lose my perilous 50+ rooms in my vault. Please help me to open my vault again. I had a good run, with 138 dwellers and highest ranking dweller was level 50, among many level 30s. I can't start again after spending weeks to construct it.
