SAGA: Fix for Bug #3324850 ("ITE (SAGA): crash in dog sewers")
This read of 1 byte past the end of the buffer has existed since
the dragonMove() function was implemented, but since the change
in bfb0986c to use ByteArray, this now causes an assertion due to
the stricter bounds checking.
This commit corrects the original issue.
Thanks to fuzzie for this fix.
