supplementary explanation.
 
	In 2.9.18.12899, Mission #5 Professionals Study Logistics finished normally, although Debrief.log grew large (around 80 MB).
 
	In 2.9.19.13478, the same mission fails to finish properly due to excessive growth of Debrief.log. The mission ends with an error and I cannot proceed in the campaign.
 
	Steps to reproduce:
 
	Start the Viggen Wrath of Thunder Mission #5 “Professionals Study Logistics.”
 
	Play normally until mission end (landing / mission completion).
 
	On 2.9.19.13478, the mission does not conclude correctly and Debrief.log grows excessively, leading to a debrief error and campaign progression failure.
 
	Expected behavior:
 
	The mission should end and show the debriefing screen.
 
	Debrief.log should remain within a reasonable size.
 
	Observed behavior:
 
	On 2.9.19.13478, Mission #5 does not end correctly (debrief error).
 
	Debrief.log grows far larger than in 2.9.18 (80 MB), preventing campaign progression.
 
	Additional info:
 
	Rolling back to 2.9.18.12899 allows Mission #5 to finish normally (still ~80 MB Debrief.log, but no error).
