Thank MrMango404 for his bug report. I completely forgot about putting water into slabs and stairs. It went into problems when you tried to place water in there. In some situations, slabs/stairs were replaced by water. Mainly water was placed outside of them. In addition, there was a huge problem with not solid blocks (like saplings, end rods, torches, wheat, etc.). They were replaced without dropping the item.

As a little bonus, this release adds a change to counting damaging value for players. It multiplies value from plugin config with the difficulty of the world where the player is. You can still configure lower values for hard difficulty mode if you need it by setting for example 0.3 in the plugin config file. There is another bonus - damaging resistance (by hot water) for players using the fire resistance potion.

Bugfixes:

• Placing water into stairs, slabs, and instead of not solid blocks doesn't work #29
• Dispenser should drop (water) bucket when there is no water block or air in front of it #32

New features:

• Swimming in the hot water without damage when using fire resistance potion #31
