From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Owen1212055 <23108066+Owen1212055@users.noreply.github.com> Date: Wed, 7 Dec 2022 17:25:19 -0500 Subject: [PATCH] Properly resend entities This resolves some issues which caused entities to not be resent correctly. Entities that are interacted with need to be resent to the client, so we resend all the entity data to the player whilst making sure not to clear dirty entries from the tracker. This makes sure that values will be correctly updated to other players.
