Plugin Help Worldguard region problem

Hi Folks,

Recently decided to upgrade a long running vanilla server. Upgraded to the latest bukkit 1.11.2 - latest stable build. Among the plugins is Worldguard 6.2.

In a creative world, I have nothing special in the world config, just something to prevent fire destroying things...

fire:
disable-lava-fire-spread: true
disable-all-fire-spread: true
disable-fire-spread-blocks: []
lava-spread-blocks: []

However, when a region is enabled...

train_stations:
min: {x: -1263.0, y: 3.0, z: 569.0}
flags: {}
max: {x: -1133.0, y: 31.0, z: 616.0}
priority: 0
type: cuboid

... itemisation of a cart, when running in to a cactus... fails. The cart comes to a stop with the player still in the cart.

I've got no idea as to why activation of this region, should cause itemisation of the cart to fail. Remove the region... and cart itemisation works no problem.

Any ideas please?

In case it is of use... here's the default global file. I can't find anything concerning itemisation.

The only thing I can think of, is that something extra is needed in here since the upgrade...
