Purchased tool kit, large bug but author refuses to respond

My team had purchased the RPG starter kit some months ago and Ive been working in it. Most of it is pretty fine other than a few smaller complaints but theres this HUGE problem where if the player tries to pick up an item, half of the time that item will not show up in the inventory and it takes a random amount of time trying to get it to work. Most of the time I have to re compile the blueprint 5-10 times. I don’t even know if that helps get it to work again because often it doesn’t so I have no idea why this problem is occurring or how to fix it. This happens in a fresh project that I start as well and the author refuses to answer any of my emails after several weeks and my team has a deadline for a rough demo next month and this is a huge problem that cant be in there. Is there something I can do to get the this kits attention through Epic or something because this is completely unprofessional of the author to overlook something this big and having to leave the people to purchase it to deal with it on their own.

Sorry to hear of the issues, you may also wish to post over, in the Forums, there is a marketplace forum there as well.
