Subject: fixed support for wrap-around levels in EM engine
X-Git-Tag: 4.2.0.3~17
X-Git-Url: https://git.artsoft.org/?p=rocksndiamonds.git;a=commitdiff_plain;h=0674fef44ec688158f1501b51371d53983ac96bb

fixed support for wrap-around levels in EM engine

Fixed initializing wrap-around levels in the EM game engine; this was
done when loading the cave, but using a run-time flag, which is not
set until starting the game.

This is a regression bug of commit 04c0f302.
