Subject: fix integer overflow (fixes #414)
X-Git-Url: http://81.2.79.47:8989/gitweb/?a=commitdiff_plain;h=183c81b5ecf4f9350936737f5091073d81733d73;p=zefram%2Fminetest%2Fminetest_engine.git

fix integer overflow (fixes #414)

liquid_kind was declared as an u8, but used to hold a content_t value, which is delcared to be a u16.

changing this fixes (at least for me) the problem reported in bug #414.
