You will get used to this. The more files you mod without checking, the higher the probability of crashing. same with amount - make 1 gun - you probs get it right...........make 100 in one sitting, and the chances are you did somethign to cut corners, and that will have increased the chance of cockup (like spelling mistake for nickname, or getting ids number/info mixed) and = crashes.
Until you get used to it, its best to check after the minimum to get something working! After that work onwards, cause otherwise, imagine it - you have 3 files modded and you have a crash, or you have 8 files modded, and a crash. Which is easier to find the crash in? Easier if you know that the first 3 work well, and then it must be last 5 or so...........
