Only the latest is required, so just the 0.15.11 patch is needed. You are overwriting the same folder with each patch, so the only one that actually applies is the last one you do.Do you need to use each patch consecutively or just the latest patch?
i.e. do I need to apply patches 0.15.1 through to 0.15.11 or just the 0.15.11 patch?
Thanks in advance
