I have so far not been able to replicate the issue on the development build of OpenRCT.
The terminal SV6R file, debug replay, dump.gz file and configuration file from my attempt to interrogate the terminal have been included. I also have an 11.2 MB full dump file if that is of use to anyone. Nothing appeard on the terminal after loading the affected save file.
NateTheDBA, please could you include an example affected save and a screenshot, as this may help the resolvers see patterns in what is going on?
