Multiplayer Project using UMG Widgets keeps crashing

I’ve been developing a multiplayer game and was using simple draw text to generate my HUD using a HUD blueprint. With the release of the new 4.6 version I decided to start using UMG Widgets. I noticed however that the engine crashes once I decide to test my game on a dedicated server. Running it on standalone works though.

My widget is just a simple health bar and a textbox which gets modified based on the player’s stats.

Has anyone else encountered this issue?
