Two exploits found

[sillyhdb]

Just unintentionally found 2 exploits in the Minecraft survival server.
1: Placing lava inside of downwards flowing water will cause the block that you right clicked to disappear. This was done on a dirt block but could likely be done on others.
2: Placing lava on top of grass (not the block but the plant) will cause the lava to visibly appear, but be static and do no damage.
Both of these were done with the Optifine and Vivecraft mods

Do the blocks permanently disappear with the first bug, and does the lava stay there if you relog in the second one?

To me it seems like these might just be visual/client side issues.

If they are, that's ok. But can we make sure they are not more? I'll get Managers+ to look into this

I tested both, #1 didn't make the block above it go poof(tried both diamond block and dirt). Placed water first down as it flowed down inside my cobblestone pillar then placed lava where I put the water. Just changed water to lava.

#2 the grass plant(not block) burnt away and I also took damage from the lava. I put the lava ontop of the grass plant.

It seems it is client side issues like Sasha said
