Worldthreader 1.5.0

Configuration

• /gamerule worldthreader_Active <true/false> enables/disables the mod
• /gamerule worldthreader_AdditionalEntityTickAfterTeleport enables/disables ticking entities immediately after teleporting from the main overworld to the nether or end to simulate the timings of vanilla portal use
• /gamerule worldthreader_CreateNetherPortalsForAllEntities <true/false> enables/disables all entities being able to generate nether portals. Fallback when no portals are generated/found: Entities are teleported back to the portal they entered, which is mostly seamless.
