Recently, i had to learn to make a MCPE server with plugins which includes PEX. Therefore if I do not understand anything, try to explain in detail to me, thanks. PM Version: Tesseract v1.2.1 for MCPE v1.0.8 Protocol 107 PHP Version: Whatever that came with Tesseract OS: Win10 64bit Creators Update Plugins: PEX, LiveXYZ PEX downloaded from (https://poggit.pmmp.io/ci/RevivalPMMP/PureEntitiesX/~) Dev#87 master Basically, my problem here is that PEX can be loaded when the server loads but no mobs will be spawning plus all previously spawned mobs will be instantly despawned/removed and I can't spawn them with a spawn egg. Here are some errors that I will get frequently when a mob tries to load in: 1. CRITICAL> ClassNotFoundException: "Class pocketmine\network\mcpe\protocol\ProtocolInfo not found" (EXCEPTION) in "/src/spl/BaseClassLoader" at line 144 2. CRITICAL> "Could not pass event 'pocketmine\event\server\DataPacketReceiveEvent' to 'PureEntitiesX v0.2.2_dev': Class pocketmine\network\mcpe\protocol\ProtocolInfo not found on revivalpmmp\pureentities\event\EventListener 3. CRITICAL> Could not tick level "world": Class pocketmine\network\mcpe\protocol\AddEntityPacket not found Possible other errors: https://pastebin.com/raw/nE0EcZUQ (but they do not appear often) Although this problem is mentioned in another PEX help thread (https://forums.pmmp.io/threads/pureentitiesx-plugin-help-loads-of-errors.2264/), it was not clear how it was resolved by the user near the end, although it was mentioned that a new version was used. However, i did try Dev#86 master but to no avail, so I would like to request some help on this problem.
