Game crashes usually have very specific causes, but any number of specific things could cause the issue for you. If there was a crash issue that we determined needed a service side fix and that fix was deployed but you are still seeing crashes then those crashes were not likely related to the crashes you are seeing.
In this case it will help if we could get some system information as per the instructions listed here:
Gather that info and reply back. Include specific details of the crash. What you are doing when it happens, are there any specific error message codes or crash report IDs etc… anything that can help us track down the cause so we can offer a solution.
