Immediately after the final battle and scrolling credits (immediately - before even turning in the quest or leaving the area), my inventory space was reduced back to the starting amount and my extra two weapon slots were removed. All of my equipment was either deleted or dumped onto the ground.
I entertained the remote idea that perhaps part of this was intentional and I would regain the lost weapon slots while questing my way through Playthrough 2. I am up to New Haven on P2 and I still only have two weapon slots.
I feel like my only options are to find a way to edit my character file to regain the lost slots or to start from scratch. I'm looking for any ideas or assistance anyone can offer with this dilemma. Thanks.
If you set it from the default of 2 up to 4, then you're future playthroughs will start you out with 4. This can also cause unwanted effect in low levels that may happen to join any game you host. If you do go that route do it like this. Change to 4. Load character. Exit game (automatic save). CHANGE BACK TO 2.
However, I recommend you DO THIS INSTEAD! Download Gibbed Borderlands Save Editor: http://blog.gib.me/2009/10/31/borderlands-save-editor-revision-10/comment-page-14/ It's fast, safe, and doesn't screw up other peoples games. You'll probably need it for when the INI modifications of someone else screw up your own game. E.g. 255 inventory spaces.
I think that The Sizemore told you to get Rick's editor revision 10...which unless I'm mistaken doesn't have a weapon slots modifier.
This one is Revision 14 which was made by somebody else, but based off of Rick's. It does have a weapon slots modifier. Its the next to last option under the first tab. http://drop.io/borderlands_save_game_editor
