I got a horse, it has a saddle and armor. I was riding this horse through the dessert and a hidden pokeball item thing so i stopped, dismounted and grabbed it. When i tried to get on my horse it was gone and i looked everywhere. I solved it by leaving the area and coming back so that the game reloaded the terrain and everything in it. When i came back the horse was right where i dismounted. Im using Pixelmon 5.0.0 beta 12 so i expected glitches and this report will most likely be helpful to you. As a disclaimer of sorts i am using other mods too but nothing that touches the horse script or the pixelmon script as far as i reason. These mods are as follows: Journeymap 1.10.2-5.3.1, Pam's HarvestCraft 1.9.4-1.10.2g, Pixel Extras 1.10.2-2.2.2, Spawn of Psyduck 1.10.2-2.3.0, Pixelmon Trainer Commands 2.0.0, wondertrade 4,4,4, Optifine 1.10.2_HD_U_D4, BetterFps 1.3.2 and of course Forge 12.18.2.2099. I have recreated this glitch one other time and solved it the same way but the second time it was a visible pokeball. I know its alot of mods, but i thought a glitch is a glitch and you guys might want to still check it out to see if you can get a horse with armor and a saddle to dissapear when you dismount for a poke item. Also i was playing single player.
