AI MoveTo bug on UE4 4.7.3

Hello

Since i ported my project to the UE4 4.7.3 The AI Behavior has been really inconsistent. Specially with the MoveTo node. it seems to randomly fail for no apparent reason sometimes the node returns fine and the Bot moves properly to the destionation, then it can randomly return that it failed as soon the node is initialized, breaking the rest of the AI Logic

Any help is always appreciated!
