Ok, so I've been experimenting/stress testing on the dedicated server and I have found some interesting results.

I loaded a mission using only the mods listed above on Stratis and ran it....no desync for hours and hours.

So I created a new mission on Al Rayak...only adding CUP Terrains and Al Rayak map to the mod list....and I get this RPT spamming over and over and over and over...causing a desync and a log file of almost 18mb after 10 hours or so.

Error in expression <tive = _profile select 2 select 1;

if!(_active) then {
_position = _profile sel>
Error position: <_active) then {
_position = _profile sel>
Error Undefined variable in expression: _active
Error in expression <active = _profile select 2 select 1;

if!(_active) then {
_position = _profile s>
Error position: <!(_active) then {
_position = _profile s>
Error !: Type Array, expected Bool
Error in expression <tive = _profile select 2 select 1;

if!(_active) then {
_position = _profile sel>
Error position: <_active) then {
_position = _profile sel>
Error Undefined variable in expression: _active
Error in expression <active = _profile select 2 select 1;

if!(_active) then {
_position = _profile s>
Error position: <!(_active) then {
_position = _profile s>
Error !: Type Array, expected Bool
Error in expression <active = _profile select 2 select 1;

if!(_active) then {
_position = _profile s>
Error position: <!(_active) then {
_position = _profile s>
Error !: Type Array, expected Bool
Error in expression <tive = _profile select 2 select 1;

if!(_active) then {
_position = _profile sel>
Error position: <_active) then {
_position = _profile sel>
Error Undefined variable in expression: _active

This looks like an ALiVE error to me. Is that correct? Anyone else seen this? It's the major bugaboo for my issue right now it appears.

If AuTigerGrad is seeing something wonky, there has to be an error dump somewhere causing the problem. He's been able to run his British Steel mission (with AiA) for days on end without any problems at all. And this was recently.

I wonder now that AiA is obsolete and he's likely changed it to CUP if that has changed. It would seem he's implying there's an ALiVE+CUP conflict going on but that would be tough to determine without an ALiVE, CBA and CUP only test.

I was refering to these errors:

if!(_active) then {
_position = _profile s>
Error position: <!(_active) then {
_position = _profile s>
Error !: Type Array, expected Bool
Error in expression <active = _profile select 2 select 1;

You do seem to get a lot of errors, judging by the RPTs you've been posting.

I'll check out the mission in a bit.
