I tried to adapt this official entities tutorial to display sprites instead of the tanks. TL;DR : I can create and render entities with a system + IJobEntity + bakers and all that good stuff correctly in the editor, but the entities are completely non-existent in a Windows build. So, I am sure there are many things not optimal about the way I am doing this but it just a huge red flag that it isn't building correctly and I just can't figure it out. This is what it looks like in the editor: The player from the build only has the cube. No error messages in the attached debugger. I added the cube to make sure that the scene was loading correctly. I added the repro above to try to save a bunch of screenshots and code snippets but after attaching a debugger to the build, but I know that the job to actually create entities is not executing. I just have no idea why. Any insights at all would be incredibly appreciated!
