This seems to be an issue with the program not executing the command properly. I have modified it to use the ohk input instead and it seems to have fixed the issue. There's alot of posts in the "Sinbot" thread but allot of disregard for the actual problem.
I've checked bindings, screen resolution, everything is run under admin, up to date on each .dll. I tried changing the delay on the speed modifier in ranges .5,1-10. Graphics resolution is lowest setting.
After changing the speed modifier to use ohks binding it seems to have resolved the issue, of course you will have to bind ohk to another key. The [kp_downarrow] seems to be a single input as the command log is not showing the input even being processed. Of course this is all on my system as many things can attribute to the inability of execution. The read me file included with sinbot is alot of common sense stuff that really is just a refresh of what was posted before even getting to the download link so

It would be easier to read through the sinbot thread but there's about 60 pages of questions that are common sense, failure to read posts and the coders that actively have worked with this program seem pretty fed up with the questions that have been answered 10+ times already.
( For any of the coders that work with sinbot that may come across this. " The program is executing properly. It appears to launch the command input for the host_timescale once then disregards it from then on out..(yes I have read all 80+ pages of "sinbot release thread") Without the timescale executed the bot fails to go far enough in winding maps, fixing it is simple if your able to sift through all the redundant executed commands and remove them.
My two cents...basing a bot around a .dll outside of command execution usually ends up exploding in your face due to bad mapping. Autoit has a feature that allows things to be slowed or increased without using a .dll that is increasing speed already.
Hope this sorta helps. If I get more time I may just modify the bot to execute properly I just need to decompile the bot to remove the code that is interrupting proper execution.
