I will submit 1.4.5 version for UE4.18 soon with a fix for issues rising on a few projects when packaging development builds, but an important note I’ve also attached to the Marketplace page:
UPDATE WARNING (UE4.18+):
Version 1.4.5 introduces a significant change in code and isn’t recommended upgrade mid project to 1.4.5 if you have many ‘Spawn from Pool’ nodes in use on your Blueprints; 1.4.5+ have moved custom BP nodes to a ‘Developer’ module which is essentially a different DLL… That means if you update from earlier versions to 1.4.5+ when you open your project in Editor all the ‘Spawn from Pool’ nodes will disappear from your graphs and you’ll have to add them again to your Blueprints because Unreal Engine considers the moved nodes in 1.4.5+ a different function coming from a different DLL although they are really the same functionality.
This change was needed to fix issues some projects had when packaging test builds in ‘Development Mode’ instead of ‘Shipping Mode’.
