Swindon Supermarine squandered a first-half lead as they went down 2-1 at promotion rivals Tiverton.
Boosted by the return of defenders Ash Taylor and Ryan Morgan to the starting line-up, Supermarine looked to build on their four-match unbeaten record.
But the Swindon side had goalkeeper Matt Bulman to thank for not going a goal behind when Owen Howe raced clean through on goal, rounding Bulman only for the Supermarine stopper to get back to make the save.
Supermarine then took the lead on 17 minutes when Ash Edenborough finished from close range after Luke Hopper’s fine run and cross had picked out the striker.
Ross Adams should have doubled Marine’s lead six minutes later when he blazed over from close range.
Tiverton left-back Mike Williams then saved the hosts from going further behind when he managed to get a foot on another Hopper centre which looked destined to pick out Edenborough for an easy tap-in.
Supermarine were made to pay for their missed chances in the second half when Dan Smith’s free-kick picked out Andrew Neal at the back post to volley home the equaliser.
Next it was the home side who were guilty of missing good chances with Richards and Neal both forcing saves from Bulman, the latter also firing wide from 20 yards.
Tiverton though got their breakthrough at the start of the second half when Howe’s deflected strike was parried by Bulman straight into the path of Western who scored.
Swindon Supermarine again had Bulman to thank for keeping them on level terms when he saved Western’s close range effort.
With the game seemingly petering out into a draw, Tiverton took the lead after breaking free from a Supermarine corner.
After James Mudge and Smith had combined to feed Neal, the striker got to the byline before pulling the ball back for substitute Alex Faux to finish from close range.
