Loading crashes when using updated techtree&odd behavior.[Multiple Projectiles]

[Coldfusionstorm]

Loading completes fine but when firing the updated cannon. The game crashes, The Crash is kinda inconsistent but change the speed of the projectile and the loading a file from the same techtree saved with the old projectile speed the game crashes , or the skill plain does not work. perhaps the game loads old cached content?.

Starting a game from scratch (not loading but simply building base from start, This does not occur and multiple projectiles work correctly).

  How to make a bugreport ....

Well please start the game from a console and show us the stacktrace/output.

[Coldfusionstorm]

I know, but i was not sure what info you needed. And if you even deemed it a bug. BrB, getting console output. (i have it set to start with that XD.

Well,I could not quite seem to get it to crash by using the attack skill and change the speed, i did however crash on loading, it also hits me that im using the 3.10 dev version i should properly update.starnova.exe v3.10.0-dev

So the steps to reproduce are:
1. Start a game with multi particle system
2. Save the game
3. Stop MG
4. Change the particle speed
5. Start MG
6. Load saved game
=> crash ?

update:
Of course you cannot load a game when you change from multi particles to single particles or vice versa. This must result in a crash.

[Coldfusionstorm]

Allmost, When loading is done.

Resume game and use the skill.

I was trying to get the skill to work, Perhaps some lingering data. But yes, What you described, was it. i haven't been able to reproduce it today tho.

What about adding exstra projetiles between loads, Would this count as changing the type of the projectile? (from single to muliple?)

[titi]

In general it does not make sense to change the data and to expect load game form an older version will works! This will never really work and its not worth putting some energy into it. In opposit we should think about saving a CRC of the techtrees xmls to savegame. On loading we check if anything was changed. If this is the case we should block load or at least warn people that this incompatible version might crash.

[Coldfusionstorm]

I use the load feature alot of testing techtree changes, it is in fact one of my test tools for testing new buildings, Tech requirements, large battles and semi-simulations of different battle sizes (ex, If changing the totalt health pool of 50 Tanks how long does it take to kill all the units with a attack of 30, Sure you can do the math for it, but sometimes you need to manipulate it, and it would take alot of time to build up such a army each time, not to mention that the build would be quite tedius, and this is just 50 tanks.

I can see what you mean tho, Is there some general check we could put in place for stuff like this?, is it even worth it?.

Also, Some people like to build a huge base or build different places, a safe game the come back to now and then.

All this is just on top of my head, Implementing CRC check might be overkill right now. And would it really safe time in the long run?.

A general error like "data mismatch", or something like that.

Or tech tree versioning stucture. so techs with same name(and uniqe game identifier), would track revisions.

But that is getting off topic, The bug report attached to this post just came when loading finished (but rendering did not start), and i pressed enter when the application stopped(megaglest froze). And simply trying to load the same file again worked.
