dig in sea or water only permits 3 blocks and then stop to dig

[mckaygerhard]

i started a game as normal player, in a water lake try to dig in deep and after dig 2 block the next one cannot be digged, its again replaced and after 4 times i can dig the block..

after futher investigations.. found that the mod its pretty complicted for my skils.. but after changin this line its seems to work:

seems its related to minetest/minetest#4388 (comment)

also noclip gives me many false positives in 0.4.X but sems in 5.X does work well , it sems the folowing patch gives me better results (i was guessed in code cos its pretty complex)

thanks in advance.. i am trying to improve your two mods: fairplay and adblock.. my idea is that adblock must use fairplay exposed api.. (Still not available of xourse) and later the patch for version string
