I have created some ships that, while in VAB, show the correct life support numbers, but while on the Space Center screen or anywhere else, when I click the TAC Life Support button to see how many resources are left, I am seeing only negative numbers. And these numbers seem to be duplicated across all of my active vessels. Also, one ship (Claude's Wreckage) is still appearing in the Life Support Monitoring window even though I have already recovered that vessel from my tracking station. I have screenshots showing the issue I'm talking about (which also shows my TAC Life Support version number), and a screenshot showing my KSP and Windows version numbers. I am also including the Player log file, and my save game files. This is a Steam copy of the game. Here is the link to the files: https://www.dropbox.com/sh/fdffwk6kb06drke/AAAaASGuBNJZwPITAfYSpKFha?dl=0

This is now fixed in V0.18.0

I'm experiencing the same problem while using TACLS V0.18.0.0 in KSP 1.12.2. The system correctly predicts LS usage in the VAB, but once the vessel is launched:

1. no LS resources are ever consumed or generated
2. the TACLS monitoring window shows the wrong vessels - it includes some that no longer exist and is missing ones that do exist
3. the monitoring window lists the remaining times as the same large negative numbers
4. the listed "last updated" time is very large

Here is my version of the info that OP included: https://www.dropbox.com/sh/cc0i611j5ij8ct9/AAByL_v2TgcpCh9gQGCElPiha?dl=0

I hope that's helpful. Thank you!
