I dont think that is applicable as it involves an integral part of my game and there is a fair amount of casting to BP’s, I actually found a work around and thought i deleted the question, however I dont think its a case that the issue was fixed more that I have made it irrelevant to my project.
I would be happy to send my project to you directly and made a few comments on the relevant parts of the BP but I think you would find it a nightmare to find the issue as it is a large BP and involves many castings. Even after all this it may just be me making an error in my blueprint not the engine per-say.
Would you like me to upload it to a dropbox and send you the link privately. just to clarify my content would still be my own and wont be used/taken right ?
thank you for your help.
