And that right there is the problem. It’s the murmur hash lib we use, ours is vendored because the original author changed the seed value of the lib (and made it non-configurable) and breaking backwards compatibility - which we can’t tolerate,
So basically if you compiled Tyk with the non-vendored version, it’s likely it generates hashes that are incompatible with the Tyk mainline 
The only option for you is to compile the latest version of Tyk Gateway yourself, but remove the murmur3 library from the vendors list so that you use the same version that your old Tyk was built to.
