Wed Mar 25 00:08:57 2009 : RoM Bot Version 2.26
Wed Mar 25 00:16:58 2009 : WARNING: Failure reading memory from 0x2D9FDB4 at 0x6c7c8cc in memoryReadFloatPtr(). Error code 299 (Only part of a ReadProcessMemory or WriteProcessMemory request was completed.)
The warning is repeated about 1027414 times in the log.
I ctrl+l to stop the current executed lua and re-execute the bot.lua and it resumes just fine.
I'm guessing you enter your house briefly, change zones, or log out and back in. The next (unreleased) version already checks if the player address changes, and updates it accordingly to prevent this exact error from happening.
