Solved Block meta value -1 is out of bounds (EXCEPTION) in "src/pocketmine/block/BlockFactory"

Hi,
Do you know this error :

2017-08-28 [08:34:09] [Server thread/CRITICAL]: Could not tick level "world": Block meta value -1 is out of bounds
2017-08-28 [08:34:09] [Server thread/CRITICAL]: InvalidArgumentException: "Block meta value -1 is out of bounds" (EXCEPTION) in "src/pocketmine/block/BlockFactory" at line 374

PMMP issue or plugin issue ?
thanks

Server configuration :
PocketMine-MP 1.6.2dev-501: PurePerms 1.4.1-dev2; AllSigns 1.0.2; ItemCasePE 1.1.0-dev1; FactionsPro 1.4.5; xyz 1.0.3; EconomyAPI 5.7.1-dev2; CrateKeys 1.0.0; AlwaysSpawn 2.2.3-dev1; KillMoney 1.1.2; Jail 1.2.0; SimpleAuth 2.0.0-alpha7; SimpleAuthHelper 2.0.5-dev1; Slapper 1.3.5; PiggyCustomEnchants 1.0.2; essentialsTP 1.2.0-dev1; ChatToDiscord 1.1.0; iProtector 4.0.1#3.1b; Parkour 1.5.6; EconomyShop 2.0.8-dev2; PureChat 1.4.10-dev2

 

Try remove all your plugins, reload/restart server, then see if the exception replicates. I'm experiencing this as well.

 

By remove I mean move them else where
