Police Quest: SWAT - Crash after Tactics Training Speech renders game unfinishable

[CTxCB]

ScummVM Version: ScummVM 2.1.0git3659-g28918638e9 (Sep 3 2018 15:06:34)

Bug Details: After completing Small Arms Training, and at the end of the Tactics Training, the game crashes with a ScummVM Error that says "[VM] kLock[4]: Signature Mismatch in method rookerTrains3::changeState! (room 6400, script 6400, localCall ffffff)", rendering the game unplayable beyond training and eliminates the possibility of the player partaking in any scenarios. I've included a screenshot of the Debugger Error.

Bug Reproduction: I've attached a Save Game as close as possible to where the bug happens. Simply, Select the SWAT Button in the Bottom-Right, Select "Travel Map", then the "To Protect And To Serve" Button on the right and finally "Yes" to the prompt "Attend Tactics Training?". After the lengthly Tactics Training Segment (which is necessary to begin taking on missions and scenarios), the game crashes.

Game Language: English.

Game Version: GOG (CD-ROM Release?).

OS Version: Microsoft Windows 10 Pro (10.0.17134, Build 17134).
